The Soul of A Vampire Book 3 — Rachel E. Rice

Sebastian's only thought was to protect Zoey and their baby by sacrificing himself to Samantha and offering her what she has always wanted -- the chance to marry him and become his queen. Sebastian thought this was a small price to pay for the life of Zoey and his baby. But where does that leave Zoey now that she's pregnant?
When Zoey discovers that Sebastian will marry Samantha, all Zoey wanted was to see him one last time and then she would be satisfied, but it didn't work out that way. Zoey decided that she would fight for him and so she devised a plan, but then all good plans of mice and men go astray and so did hers.
How can Zoey live with the knowledge that Sebastian has married a witch and the witch will never let her live long enough to give birth to a vampire baby?
