The House of Mourning - Suzannah Rowntree - Bog

From the demon-infested shadows of an enchanted house, a sorcerer plots the downfall of the crusader kingdom...and his greatest act of vengeance.
Jerusalem, 1186: They call her the White Watcher, the warrior saint guarding the beleaguered kingdom of Jerusalem with her invincible lance. But Marta Bessarion doubts she's anything special - and all signs warn of a coming disaster.
Now allied with the demon Lilith, the cunning and ruthless Countess Sibylla is poised to seize the throne. In Damascus, Saladin has sworn to conquer the crusader kingdom. And at his side, the sorcerer Khalil plans to take his revenge on the Bessarion family once and for all.
War promises Marta a long-awaited chance to confront Khalil, but in order to defeat him, she must first uncover his darkest secrets...and venture to the heart of his power.
Some battles can't be won, even with a magic lance.
Sometimes it takes the weak things of the world to put the mighty to shame.
Darkly gothic and steeped in magic, this is the pivotal fifth instalment of the critically acclaimed Watchers of Outremer historical fantasy series!
