The Tattoo of the Elf [The Triplet Mermen Trilogy‪]‬

Jefferson Workman, an elf, is instantly attracted to the merman he bumps into outside the public library, but he has no idea how to get in touch. He doesn't even know the merman's name. He won't ever forget those enticing icy blue eyes, though. He's saved from his constant pining when he's tasked to deal with an evil sorcerer who attacks supernatural beings at random. Baltic Pelagius, a merman, is astounded by his instant attraction to the elf he briefly talks to because he hasn't felt something like that for a century. However, he dares not hope for a happy ending. He's an abomination due to the siren magic within him which urges him to lure men and women to their deaths. He also has to contend with a sorcerer who uses dark magic on him. Then, he crosses path once again with the elf. Can Jefferson and Baltic work through their issues together while fighting against the evil sorcerer?
