The Blackwood Curse 3: White Knight - Paperback

Well, I successfully closed Alistair's para-dimensional gateway, but life in Woodhill hasn't returned to normal. Claire is still in Alistair's clutches, lost somewhere in the multi-verse, and I have no idea where or how to find her. Then a clue arrives in the form of a message from Alistair and a deed to a house that once belonged to Alistair's great-grandfather. Somewhere in the house is an artifact that Alistair needs in order to bring his hideous goddess back to conquer Hal's world.
If I can find the artifact, maybe Mora and I can use it to get to Alistair...and Claire. Meanwhile, Claire's younger brother Nathan has been increasingly impatient and anxious about his sister. If I don't find the artifact soon, I may have two children to rescue in addition to stopping Alistair's megalomaniacal ambitions. This time, I won't be able to do it alone.
