I KILLED ZOE SPANOS is an engaging YA thriller. The book switches between the present and a few months earlier, when Anna was babysitting in the Hamptons. The book begins when Anna is coerced into a confession that she killed the missing girl, Zoe. But did she? This is unclear, especially as her memories of the night Zoe disappeared are spotty at best.

Anna has an alcohol/substance abuse problem that she is trying to escape. She would frequently go partying and then forget herself and/or what she had done. She is hoping that taking a job nannying will help her to leave that life behind. Being a nanny in the Hamptons is complicated by the fact that she looks a lot like Zoe Spanos. As more people make the comparison, Anna begins to look into the people and the case as much as she can, but her own questions are increasing.

What I loved: This book hooked me pretty early with wanting to know what really happened to Zoe Spanos, and the answer is very complicated. The book also includes podcasts that really add something special to the plot. The end gets a thrilleresque feel as Zoe's murderer is on the trail, and Martina, Zoe's little sister Aster's BFF, is making podcasts, trying to figure out what happened to Zoe. This is a solid plot, which is paced slower at first and much faster later on. The reveals at the end were top-notch, really bringing everything together beautifully.

Final verdict: Perfect for fans of SADIE, I KILLED ZOE SPANOS is a clever and engrossing YA mystery/thriller that will keep readers guessing to the end.
