What to expect

‘Stunningly brilliant… Full of more twists and turns than the best ever rollercoaster, with an epic ending’ NetGalley review ⭐⭐⭐⭐⭐


When six-year-old Marcus is taken from outside his house on Halloween it shakes his quiet neighbourhood to the core.

Everyone was ready for a night of trick-or-treating. Now the unthinkable has happened.


As Detective Imogen Grey arrives to question Marcus’s parents, they tell her there has been a mistake. Their son is just fine.

But if that’s true, where is Marcus?


Imogen becomes locked in a race against time to find the missing child and uncover the truth. Can she discover what’s happened to Marcus before it’s too late?

A completely addictive page-turner, perfect for fans of Cara Hunter, TM Logan and Shari Lapena.
