Locke & Key (Omega #4)

For month after month, a demon named Dodge has struggled to obtain the omega key, so he can open the Black Door... a portal to another dimension secreted in the depths of the drowning cave.
Once the door is unlocked, there will be nothing to stop Dodge from bringing through a legion of beings just like him.
The children of the Locke family — Tyler, Kinsey and Bode — have stood alone against this tide of darkeness, holding Dodge at bay with imagination and courage...
...And the many other medical keys to be found in their ancestral family home, Keyhouse.
Their bravery and resourcefulness wasn't enough.
Dodge took control of the body of the youngest Locke, casting Bode's soul adrift in the shadowed halls of Keyhouse.
In the costume of Bode Locke's flesh, he soon laid claim to the omega key.
Only one person has seen through Dodge's latest disguise: a mentally challenged child named Rufus Whedon.
Rufus's one attempt to rid the world of Dodge earned him a beating and a trip to the secure wing of a mental institution.
On the night of the senior proml, following a long standing tradition, many of the students of Lovecraft Academy have gathered in the drowning cave for a final revel.
But Dodge has a whole different kind of party in mind...
