Undertow is the 7th novel in Rainbow Award-nominated M/M Fae Soul-Shares series by Rory Ni Coileain. Rhoann Callte, Rhoann Half-Royal, is an impossible Fae. As a shape-shifter, he carries the blood of Fae water elementals and has a once-in-a-generation healing gift. Which is his blessing, or his curse, depending on how you look at it—his gift is needed among the exiled Fae of the Demesne of Purgatory, and he's coerced from his beloved solitude and sent on a one-way trip to the human world. Vietnam veteran Mac McAllan has been through hell in the last few months, and not just because his new C-leg isn't performing up to spec. He and his partner of 34 years, stocky bald muscle bear Lucien de Winter, were working at Purgatory when what the owner said was a gas explosion collapsed the building—and put Lucien into a coma back in August. Now it's October, and an impossibly handsome stranger says he can heal Lucien. But there's always a price...A Fae who wants only to be left alone, SoulShared with a human who's already found the love of his life...and the Marfach testing their incomplete bond, seeking the key to its watery prison. What could go wrong?
