Pumpernickel [EPUB ebook] 
Curse of the Corpse King

‘No good can come of cheating death.’ When her adoptive mum falls ill, Pumpernickel — a changeling that has embraced her human parents — embarks on a quest for a magic potion that could save her life. The only problem is that it’s made up of forbidden ingredients, the gathering of which would make her an enemy of all of Faery. But none of that will matter if she can’t survive a meeting with the Corpse King. It’s time for Pumpernickel to pick a side, once and for all. Pumpernickel: Curse of the Corpse King, by Luke Cooper (Hollow Girl, Alone Not Lonely) is the third book in the series and puts the little changeling up against the ultimate enemy: death itself.
