Read. This. Book.
Ok. Really, what you need to do is start with the first in the series (Beekeeper's Apprentice) and read in order of publication. At the very least you need to read The Language of Bees because this one starts literally minutes where the prior leaves off.
And it is so so so so good.
I'm not sure how to talk about this book without giving away major series spoilers. MAJOR. So let me say this for those of you who aren't caught up: go read the prior books and then read this one. Trust me.
Laurie King makes Robert Downey's Holmes look like a buffoon. Her adaptation is respectful, well researched, and intelligent.
"The great marvel of King's series is that she's managed to preserve the integrity of Holmes's character and yet somehow conjure up a woman astute, edgy, and compelling enough to be a partner of his mind as well as his heart." - Washington Post Book World.
There. And at the risk of being redundant: read this.
We left with the family split apart - arrest warrants, Mycroft has been questioned and then abducted, Brothers may or may not be dead (depending on who you're asking,) Holmes has fled with Damian in search of medical attention, and Russell is the unlikely care-taker of Holmes's (SURPRISE!) granddaughter. They're in the far reaches of Scotland, headed in different directions and this is a time when phones are hard to find and cell phones are unheard of. They may or may not have murderous madmen on their tails and both are hampered. Over the course of the next few days, plots are created, revealed, and cast aside. There's a funeral, a man who seems to have walked out of a fairy tale, an unlikely surgeon, an equally unlikely confidant, and a mastermind...there's also gunfights, snipers, disguises, and secret messages.
The God of the Hive is King herself.
(Ok, it's not but you couldn't have imagined that I would spoil it THAT MUCH for you, right?)
