Identical twins. Identical DNA. Identical suspects. It’s Pretty Little Liars meets Revenge in this edge-of-your-seat thriller with a shocking twist.

When they were little, Lexi and her identical twin, Ava, made up a third sister, Alicia. If something broke? Alicia did it. Cookies got eaten? Alicia’s guilty. Alicia was always to blame for everything. The game is all grown up now that the girls are seniors. They use Alicia as their cover to go out with boys who are hot but not exactly dating material. Boys they’d never, ever be with in real life.

Now one of the guys Alicia went out with has turned up dead, and Lexi wants to stop the game for good. As coincidences start piling up, Ava insists that if they follow the rules for being Alicia, everything will be fine. But when another boy is killed, the DNA evidence and surveillance photos point to only one suspect: Alicia. The girl who doesn’t exist. As she runs from the cops, Lexi has to find the truth before another boy is murdered. Because either Ava is a killer…or Alicia is real.

I’ve known of The Third Twin or a while, but I finally bought it not too long ago and I can’t believe it took me so long to finally pick it up and read it!  It has been a while since I’ve read a good mystery – I literally could not put it down!  The story was engaging and I kept trying to come up with my own theories as to what exactly was going on.  When everything was revealed at the end, I felt like I should’ve known earlier, but eh… I didn’t.  That’s what makes mysteries fun, right?

The twins were pretty stereotypical in terms of fictional twins – one is more outgoing and the other is more reserved and studious.  However, Lexi does get out once in while to go on an occasional date as Alicia.  I definitely related to Lexi more so than Ava.  Though both girls are pretty shallow when it comes to using Alicia as their alter-ego and dating boys that they aren’t serious about, but I suppose their flaws are what makes them believable characters.

Again, I thoroughly enjoyed this book and highly recommend it to the mystery/thriller lovers out there!
