Mystery Guest

From the author of Escape Room comes a thrilling whodunnit. Three people all confess to murdering the same person, they all have motives, but only one is the true killer.

Guess who?

Maria's life spirals into chaos after she provides testimony that puts her brother behind bars, a decision that has fractured her family and left Maria isolated from her friends. And not long after, Maria is found dead.

Three of her peers--Cody, Norah, and Pip--all confess to the murder. And they all have a motive...but only one is guilty.

When it comes to light that Maria was being tormented by a mysterious, masked figure known only as the "Mystery Guest," the search for answers becomes even more complicated.

Who is behind that mysterious mask? Who is the mystery guest? Maren Stoffels masterfully plays with perspectives and motives, as only she can--resulting in a murderously exciting page-turner.
