A murky past. A forbidden love. A deathly power.

When the river spits Umbra onto its bank, naked and shivering, the only clue to her identity is the arcane brand seared into her skin. A brand hunted by both a murderous necromancer and a handsome stranger. A brand that thrusts Umbra into a simmering conflict between the ascendant Clans and the nomadic Gherza. A brand that may make her the key to averting all-out war.
The Tree of Souls weaves an intimate tale of dark sorcery, doomed love, and implacable revenge, amid an age-old clash of nations, with all the souls of the living hanging in the balance.
