I saw The Prophecy of the Sisters by Michelle Zink over on Bloggin Bout Books. It is apparently the first in a triology, and it sounds pretty intense. The description from Amazon:
“An ancient prophecy divides two sisters- One good…One evil…
Who will prevail?
Twin sisters Lia and Alice Milthorpe have just become orphans. They have also become enemies. As they discover their roles in a prophecy that has turned generations of sisters against each other, the girls find themselves entangled in a mystery that involves a tattoo-like mark, their parents’ deaths, a boy, a book, and a lifetime of secrets.
Lia and Alice don’t know whom they can trust.
They just know they can’t trust each other.”
The Coral Thief is the new historical fiction novel written by Rebecca Scott, the author of Ghostwalk, a novel which I have been meaning to read since it came out in 2007. This one is set in post-revolutionary France. And the main character is a medical student. Sounds up my alley!
