Howl of the Heart

Lena Stormrider, a feisty, independent werewolf who has no interest in marrying for power, has consistently disregarded the Shadowfang pack's norms. However, everything she believed to be true about love and loyalty is destroyed by a single, intense night spent with Kai Blackthorn, the heir to the opposing Blackthorn pack. What started out as a brief moment of escape turns into a tempest that could destroy their worlds.
An unanticipated result of Lena and Kai's forbidden desire is a pregnancy that may spark conflict between two rival packs. The mystery of their connection, a love that has the power to either save or ruin them both, haunts them both. Lena must make the painful decision to either walk away and lose the one thing that has ever made her feel fully alive or risk everything—her pack, her future, and the love she has battled so hard for—in order to protect the kid she never asked for as the full moon rises.
However, the stakes are higher than anyone could have predicted. In addition to being the heir to both packs, their child—the result of this prohibited union—is a powerful force that has the ability to change the course of their planet.
A startling betrayal threatens to shatter the tenuous peace that Lena and her family have worked so hard to preserve as she fights to keep them together. The ultimate test of devotion, love, and sacrifice must be faced by Lena and Kai after the truth about their child's fate is made public. However, there is not much time left, and the last conflict might be the end of their entire existence.
Will Lena and Kai's love withstand life's trials or will the burden of their packs' history cause them to split up forever?
