A Stitch in Crime - City of Devils

Assembled from the corpses of six women, Jane Stitch is haunted by impulses she can't control and memories that aren't hers. When she returns to her hometown to solve the mystery of her creation, she finds herself drawn unwillingly into a war between rival gangs of monsters for control over the patch of desert she once called home.

Her creator, the only one who knows where she came from, has an agenda of his own and it doesn't include helping Jane put to rest the ghosts of her past lives. In the desert, among thundering herds of giant ants, in the shadow of a frozen blob, Jane is determined to solve the riddle of herself.

Or die trying.
