Genuine Fraud by E. Lockhart is out now. It was a different read for me and while I liked it, it was one that I put down pretty easily. It definitely reminded me of The Talented Mr Rilpley, obviously with female characters. Lots of sneaky twists and turns.
Description.
The story of a young woman whose diabolical smarts are her ticket into a charmed life. But how many times can someone reinvent themselves? You be the judge.
Imogen is a runaway heiress, an orphan, a cook, and a cheat.
Jule is a fighter, a social chameleon, and an athlete.
An intense friendship. A disappearance. A murder, or maybe two.
A bad romance, or maybe three.
Blunt objects, disguises, blood, and chocolate. The American dream, superheroes, spies, and villains.
A girl who refuses to give people what they want from her.
A girl who refuses to be the person she once was.
Ebooks, romance, fantasy, YA, crime and urban fantasy... occasional sci fi. Apparently all of the books.

I don’t think I have tried this author, but love that it had twists.
Very much so! She has another book too, which I’ve not read which is apparently good too!
