SYNOPSIS: (From Goodreads)

After the tragic death of golden boy Will Ashford, everyone in town is in mourning. Or almost everyone. Seventeen-year-old Mackenzie couldn’t be more relieved. Because she knows Will’s veneer of perfection hid something dark and dangerous. It was a truth she learned one night at the Ashford house and swore never to tell.

But her plan is threatened when she starts receiving texts from an unknown number. Someone knows the secret Mackenzie has tried so hard to hide―and they are determined to reveal it.

When Mackenzie’s former best friend is found dead, she is convinced the anonymous texter is connected to her murder, and she will stop at nothing to find them. But doing so will mean confronting the trauma she’s fought so hard to suppress and exposing the dark secrets her town has tried to keep buried―or risk being the next girl dead.

REVIEW:

**A copy of this book was provided by the publisher via NetGalley in exchange for an honest review.**

I love a good YA thriller, especially one filled with secrets, suspicious characters, and plenty of unexpected twists. Look What You Did definitely delivered! The story follows Mackenzie, a teenager who knows the town’s beloved golden boy wasn’t nearly as perfect as everyone believed. When anonymous messages start threatening to expose her secrets and another tragedy strikes, things quickly spiral out of control. I was hooked and couldn’t wait to see how everything would unfold!

One of my favorite things about this book was how many twists and surprises were packed into the story. Every time I thought I had a handle on what was happening, another secret would come to light and make me question everything. The pacing was great, and there was always something happening to keep me interested. I especially enjoyed the mystery surrounding the characters and trying to figure out who could actually be trusted.

There are some pretty heavy topics throughout the book, so this definitely isn’t a lighthearted YA mystery. There is also plenty of teenage drama, but I thought the darker elements and suspense kept the story interesting. With so many secrets and complicated relationships, there was certainly no shortage of drama!

Overall, Look What You Did was a really enjoyable four-star read! Kaitlin Reilly did a great job keeping me guessing and throwing in enough surprises to keep me entertained from beginning to end. This is exactly the kind of twisty YA thriller I enjoy, and I’ll definitely be keeping an eye out for more from this author!
