Karen M. McManus is a bestselling mystery author known for her twisty, fast‑paced YA thrillers. I have been obsessed with her books this month. I bought lots of them of Vinted®, for very cheap prices! Her books usually follow a group of teens caught up in a shocking crime or dark secret, where everyone seems to be hiding something. With lots of red herrings, cliffhangers, and big reveals, her stories keep you guessing right until the end. She’s especially popular with readers who enjoy school settings, complicated friendships, and trying to solve the mystery before the final chapter.
