The Third Twin by C.J. Omololu

When they were younger, identical twins Lexi and Ava made Alicia up to get out of trouble. If something was broken, Alicia did it. As they got older, the girls used Alicia as sort of a safety net for dating wilder boys. Ava only dates boys with potential and money, while Lexi is too focused on school to date, but Alicia has less standards. 

One night, Lexi as Alicia goes on a date with a boy who Ava as Alicia has dated before. He tries to rape her, she fights him off and escapes. Just one day later, that boy turns up dead. It seems like just a meaningless tragedy, then other strange things start to happen. They get sent speeding tickets for Alicia, and receive phone calls for hair appointments for Alicia. Alicia's Facebook page is full of pictures that neither twin took. Someone ends up changing the password and locking them out. Then another of Alicia's dates ends up dead.

Police want to arrest both of the twins, but Lexi takes the blame. They still need to find the killer. Lexi starts to suspect that it might be Ava. After all, Alicia isn't real...or is she?

The Third Twin was a pretty exciting mystery. It's an intriguing concept that kept me guessing through the whole book. Part of me wanted to just flip ahead, but I managed to resist the urge and read the whole thing. It was a fast-paced thriller, and a nice change of pace from what I usually read.

I received my copy of The Third Twin from Netgalley and Edelweiss, courtesy of Delacorte Books for Young Readers. It's available for purchase now.
