Semra is one of those children, and she knows the truth: there is a dragonlord in the mountain, raising the children into his personal syndicate of assassins. When seventeen-year-old Semra learns they aren't fighting evil but are in fact evil themselves, she risks everything to expose the dragonlord.

They must leave the Walled City to seek wisdom that will save everyone they love.

She thought these brutal experiences made her ready for anything.

Miss Mildred Percy is a spinster. She does not dance, she has long stopped dreaming, and she certainly does not have adventures. That is, until her great uncle has the audacity to leave her an inheritance, one that includes a dragon’s egg. The egg—as eggs are wont to do—decides to hatch, and Miss Mildred Percy is suddenly thrust out of the role of “spinster and general wallflower” and into the unprecedented position of “spinster and keeper of dragons.” But England has not seen a dragon since…well, ever.
