Forever, Promise Me Series, #16

Navigating the many pitfalls of being bound to the demon Shaker, human Sarelle uses him to force a peace with the vengeful vampire lords. Yet she cannot escape her Oathed vampire Danial's command to engage in a menange-a-trois with her shifter ex-husband, Theo. Sorceress Rene magically intervenes, going in Sar's stead only to be bespelled herself into having Theo's son, Harrison. Secrets long hidden are revealed, as Sar, Lash, and their son are hunted throughout the northeast by the vengeful Valarian and his forces, climaxing in a final bloody reckoning. In the end, Sarelle must face her ultimate tests: to reconcile with loved ones who have betrayed her...or to finally sever the bonds between them, forever.
