Embassy of the Dead by Will Mabbit
When Jake opens a strange box containing a severed finger, he accidentally summons a grim reaper to drag him to the Eternal Void (yep, it's as fatal as it sounds) and now he's running for his life! But luckily Jake isn't alone - he can see and speak to ghosts.
Jake and his deadly gang (well dead, at least) - Stiffkey the undertaker, hockey stick-wielding, Cora, and Zorro the ghost fox - have one mission: find the Embassy of the Dead and seek protection.
But the Embassy has troubles of its own and may not be the safe haven Jake is hoping for.
I've just finished Embassy of The Dead and it's amazing. Like an early Neil Gaiman. I can't wait to recommend it to all our young readers. It's fantastic (Fayth, Librarian)
Praise for MABEL JONES: Delightfully nasty, bonkers piratical fun. I laughed out loud! (Robin Stevens, author of Murder Most Unladylike)
A uniquely wild and witty ride. If Lewis Carroll were writing for Monty Python, I imagine it might look something like this (Christopher Healy, author of the Hero's Guide series)
