The Cracked Altar. The Cracked Altar, #1

A Missing Princess. A City Under Siege. A Compendium Of The Blackest Sorcery. The Grand Mage of Caragol is the most dangerous man in the realm, so when Kerstin steals his spellbook right out of his tower she lights up a firestorm of trouble. His fury rages through the city of Klomm. Houses burn. Innocents lie slaughtered in the streets. Yet countless lives are a petty sum for such great deal of power.
With the spellbook, Kerstin can contend with the unspeakable horrors conjured by the Grand Mage. But she is dancing on a spider's thread. Meanwhile on the other side of the kingdom, fifteen-year-old Hinkle walks a tightrope of her own, spinning a web of dangerous lies around her new master, Sir Gilkrist of Lothellae. When Sir Gilkrist's quest brings them to Klomm, she discovers the secrets she's been hiding are darker than she ever imagined.
A diabolical scheme threatens to engulf the world in shadow and blood - and it has everything to do with her Aunt Kerstin. But can Sir Gilkrist help her ... or will he devise a dark purpose of his own?
