Spell of the Black Unicorn (Chronicles of Zofia Trickenbod Book 1)

Zofia Trickenbod, a sorceress from another planet is stuck on modern-day Earth. Things have been quiet for the past three years, until one morning she finds her long-lost husband Dorian on her doorstep. And he's undead.

Meanwhile, the evil wizard Vaseelvod Blood is hypnotizing Zofia's neighbors in order to get the magical Stone of Irdisi back from her - and maybe kill Zofia in the process.

After Blood abducts her children, Zofia has to deal with a nasty demon, get past a dragon, deal with a lamia, save her children, and tell her boyfriend that her husband is back.
