When hot-as-hell Danielle Lang showed up and asked me to teach her about sex, I thought I was hallucinating. Turns out the beautiful psychologist needed an extra bit of schooling in all things sexual so she could teach a class. I'm always up for helping a friend. I mean, it's the least I can do. What I wasn't expecting is for her to turn the tables and teach me a few things. Only this short-term promise of two weeks in her bed is going by a little too quickly. Not that I'm thinking forever or anything.

I’m a single dad focused on taking care of my high-functioning son and running Boston’s Burgers and Brews, the family pub. When the girl next door, the one who’s always been there to lend a helping hand, shows interest in a firefighter friend, I’m determined to help her get her man - even if it means going undercover as her boyfriend.

Callan: I’m a single dad, a firefighter, taking it one day at a time and trying to keep my life from imploding. Once I had it all, but tragic events changed my trajectory, and now I’m raising my daughter alone. When an old friend gets an unwelcome message from her ex, I jump in to play the part of pretend boyfriend. Harmless, right? But I wasn’t counting on her touch awakening things in me.

Jaxon Hall gave up raising hell the day he became a dad - there’s no greater rush than seeing his little girl’s smile. Now if he could just convince his in-laws that he’s a responsible adult, fully capable of raising his motherless child. Every girl in Rachel’s sorority wants the smoking hot mechanic next door, herself included, but a man is the last thing she needs in her life - especially a tattooed single dad with a reputation as a badass. A man like that draws attention, and a woman hiding out from an abusive ex needs to keep a low profile.

Cole Sullivan made a battlefield promise to his best friend to take care of his little sister, but that vow, given to a dying man, has pushed the woman he's wanted for years even farther from reach. Gemma Mathews has crushed hard on the darkly handsome, far-to-serious explosives expert since she was a teen, but the sting of his rejection is as fresh as if it happened yesterday.

We're not free to give into this. She's 19, and I'm 38. And I'm her boyfriend's father. Unfortunately, they both just moved into my house.

Every family has a black sheep. In the infamous Casso crime family, that black sheep is me - Cannon Freeman. Except I’m not a free man. I’ve never been free. Not since the day I was born. I owe my loyalty to my father, Dominic Casso, even if he won’t publicly acknowledge me as his blood. I’ve never had a reason to go against his wishes...until I met her. Drew Carson turned my world upside when she walked into my club looking for a job. Now, my honor and my life are on the line.

Gracelyn Riley married a firefighter and knew that came with risks. But she never imagined herself widowed in her early 30s with two children to care for on her own. Even though her marriage to Chad Riley had its difficulties, dealing with the last year without him has not been easy. Her brother-in-law, Matt, has been the rock that has kept her from collapsing or imploding. As a Mason Ridge fireman, Matt Riley had been at the scene when his brother, Chad, was killed. For the last year, Matt has suffered from survivor’s guilt and drank himself into oblivion. Gracelyn's friendship has pulled him through time and time again until he finally sobered up.

Being in lust with my dead brother's wife pretty much guarantees that one day I'll be the devil's bitch. But Eden Gordon works with me, so it's getting harder and harder to stay away. I promised my family - and him - I would, though. My days as an MMA champion are behind me. But whenever I see her, with those wicked curves and soft mouth created for dirty deeds, it's a knock-down fight to just maintain my distance. "Hard Knox" becomes more than just the name of my tattoo shop. However, surrendering to the forbidden might be worth losing everything...

I like my sex dirty. It takes a hell of a lot to tilt my moral compass, and I always follow when it's pointing at something I want. That goes double when it points straight at the one girl in all of Chicago who's not dying for a piece of me.

Stella Lane thinks math is the only thing that unites the universe. She comes up with algorithms to predict customer purchases - a job that has given her more money than she knows what to do with as well as way less experience in the dating department than the average 30-year-old. It doesn't help that she has Asperger's and that French kissing reminds her of a shark getting its teeth cleaned by pilot fish. She decides that she needs lots of practice - with a professional - which is why she hires escort Michael Phan.

Life is smooth sailing until these new roomies find themselves stuck between a rock and a very hard place. Because lusting after the one person you shouldn't ever mess around with - your new roommate - is like cardinal rule number one. Get ready for four complete friends-to-lovers rom-com standalones: The Room Mate, The Play Mate, The House Mate, and The Soul Mate.

That time I had the brilliant idea to ask my good friend for lessons in seduction.... Awkward? Maybe. But how else is a good girl going to find out if she likes being naughty? And Gabe is charming, trustworthy, aces at seduction (or so I hear), and willing to give me lessons. But to guarantee it won’t ruin our friendship, I want these classes to be hypothetical more than hands-on. So what if he’s hella sexy? I can handle that, no problem.

One night was all it took, and I forgot everything and anything except the sexy fighter in the ring who sets my mind ablaze and my body on fire with wanting. Remington Tate is the strongest, most confusing man I've ever met in my life. He's the star of the dangerous underground fighting circuit, and I'm drawn to him as I've never been drawn to anything in my life. I forget who I am, what I want, with just one look from him. When he's near, I need to remind myself that I am strong - but he is stronger.

I'm a rescuer. It's in my DNA. Stray dogs. Stray women... But this one doesn't need rescuing. She needs something real, but I never keep the ones I rescue. I could let her go...but I can't watch her walk away. I'm an ex-Navy SEAL, and I never give up on a mission.

Billionaire software developer Parker Braxton knows everyone wants something from him. That's why he made a multi-million-dollar bachelor pact with his friends to never marry. But he never counted on running into, literally, the quiet but sensual Layla Fallon.

When he wins a sexy bet, billionaire Linc Blair can't wait to get Lauren Neill naked. He's never gone for her type in the past, and he's pretty certain it has more to do with her buttoned-up hotness than the nagging sense that something is missing from his life. But when he gets a glimpse of the vulnerable woman beneath the conservative, yet oh-so-sexy clothes, it's a game changer.

Cole Sullivan made a battlefield promise to his best friend to take care of his little sister, but that vow, given to a dying man, has pushed the woman he's wanted for years even farther from reach.

Former Navy SEAL Josh Steele gets tasked with a babysitting mission—watch over his boss's daughter—a job he can only describe as hell. But when his assignment takes him to a tropical island, and he begins to see another side of Holly Fairfax, attraction sizzles between them—but he knows better than to risk his job for it. Holly can't believe that underneath those baggy clothes tech-guru Josh Steele is all ripped abs and sexy hotness.

Trading pleasure for information is no way to catch a criminal...or is it? With 50 grand at stake and a star witness missing, bounty hunter R. A.

There's only one person he wants on the trip with him, the one who's always been there for him.

When she finds he is a dom who requires her complete surrender, even when it comes to submitting to his best friend, Trevor Wellington, she finds herself willing and eager to embrace the sexual adventure. From their earliest days, Cade and Trevor have shared everything, including women. Yet it only takes one night with Riley to know she is their forever lady.

From the first time I meet Leo Montgomery, I know I'm in trouble. His dark, heated gaze skittering down my body sets my skin on fire. A rare sighting of his elusive, heart-stopping smile and - dear lord - I think I just ovulated. But then, he hires me to babysit his adorable little troublemaker after school, and now, my maternal instincts are working overtime.

Hot Southampton doctor Carson Reynolds isn't the kind of man Gemma Carr should be playing with. But his offer of a fake engagement comes with sexy, late night house calls, and despite her bad girl reputation, it's been far too long since she's taken two and called anyone in the morning.
