Why we recommend it

The Thrall series lives up to its name, and this seventh installment delivers the captive-captor intensity and dark power exchange its readers crave. Expect a dominant, dangerous hero, an atmosphere thick with control and surrender, and the kind of high-heat menace that pushes boundaries. A bold pick for experienced dark-romance readers who want their devotion served with sharp edges. Mind the heavy content.
