Quando surge um processo seletivo para liderar um projeto de neuroengenharia da Nasa, ela se faz a pergunta que sempre guiou sua vida: o que Marie Curie faria? Participaria, é claro.

Depois de sair algumas vezes com Jeremy, ela percebe que sua melhor amiga gosta dele e decide juntá-los. Para mostrar que está feliz com essa escolha, Olive precisa ser convincente: afinal, cientistas exigem provas.

And yet their chemistry is undeniable.

Ryder, Garrett, Kenzo, and Diesel - The Vipers. Their deals are as sordid as their business, and their reputation is enough to bring a grown man to his knees, forcing him to beg for mercy. They are not people you mess with, yet my dad did. The old man ran up a debt with them and then sold me to cover his losses. Yes, sold me. They own me now. I’m theirs in every sense of the word. But I’ve never been meek and compliant.

Obituary writer Nadine Barbault doesn’t mind being called “Lady Death”. It suits the ice queen persona she’s cultivated to survive the fast-paced Toronto Herald.

Nadine’s screw-up has brought Wesley Chen of the rival Spear no end of joy—she’s been a thorn in his extremely ambitious side for years. But the renewed interest in Dot also surfaced chatter about a mysterious past scandal.

Hockey coach Ashley Jaswal doesn't take nonsense from anyone … except her overbearing and superstitious family. They believe she's a good luck charm for her brother Jas, the newest Vancouver Canucks draft pick, forcing Ash to attend all his games as he rises up the NHL ranks, sacrificing her personal life (not that she has one—who decided hockey season needed to be 10 months long anyway?). Ash also clashes with Jas’s teammate, Canucks captain Devin Snyder.
