Nokken

Lucy Kincaid wanted a simple life with a white picket fence, but after Jens took her to Undraland, she knew that wouldn't be in the cards.
Learning to maneuver the landmines of laplanding with her boyfriend's best friend is more than Lucy bargained for. Prince Jamie has access to Lucy's every thought, making it impossible to have a moment to herself, or run away from her problems. Pesta, the evil Siren, wants Lucy dead, and will stop at nothing to protect her kingdom that slowly sucks the life from the magical people of Undraland.
Nik and Jens lead the way with Lucy as they battle innumerable foes to tear down Pesta's portal in Nøkken.
Nøkken is book two in a nine-part fantasy romance series written by USA Today Bestselling Author Mary E. Twomey.
