The Raven - Spirits of the Norse, #2

Tides of change crash hard against those who resist. Magnus Haraldson has to work twice as hard to prove he is as much a Viking as his older brother and chieftain, Gunnar. When the latter gets it in his head to arrange a marriage for Magnus, he refuses. After all, there's too much of the world he's yet to see. A chance journey to Dublin changes his path and his mind. Elspeth MacAlpin follows her brother to Dublin for adventure, but she is not prepared for the new life that is mapped out for her once she meets the mysterious and unforgettable Magnus.
Apart, they are tethered by an invisible and undeniable bond. Together, their passion burns bright enough to disintegrate everything in its path.
