I seem to be reading a lot of YA lately. Not sure this is the best reading for actual YA, but it’s a great story to read to your kids. I read it on my Kindle, and I loved it. The prose are wonderful, and the story is unique.

Most of Milrose Munce’s friends died, some time ago, mostly in gruesome accidents in the school science lab. Bored Beulah, for instance, fell asleep into a vat of hydrochloric acid, there’s also Toasted Theresa, and  Deeply Damaged Dave.
Milrose is the only one, as far as he knows, who can see these ghosts. When the school administrators see Milrose talking with and slapping non-existent friends on the back, Milrose is sentence to receive Professional Help. Even Milrose and his new (real, alive) friend Arabella know there is something deeply disturbing about the Den Master,  Massimo Natica.  In a hidden room in the school: the loathsome, perilous den,  Milrose and Arabella, soon discover that they have in fact been caught up in a vast and unspeakably evil plot, which threatens the lives and deaths of everyone they know. Luckily, they have an army of ghosts at their disposal.

This book may have been written by an adult, but believe kids this age can be just as inventive when it comes to plotting the diabolical.
