Theo. The K9 Files, #34

After Sasha's father, Jeremiah, dies under suspicious circumstances, and his beloved War Dog Captain disappears, the last thing she expects is for Theo McDonald-the man she never quite got over-to arrive in Hawaii. He's here to find Captain, to uncover a dangerous secret, and to confront a past that refuses to stay hidden. What begins as a search for Captain quickly turns into a deadly hunt through hidden fortunes, long-buried crimes, and ruthless enemies, who will stop at nothing to claim what they think they're owed.
As Sasha and Theo dig deeper, they uncover a shocking inheritance, a trail of lies, and evidence that Jeremiah's death was no accident. With danger closing in and old feelings reigniting, they'll have to trust each other if they want to survive-and maybe, finally, build the life they were always meant to share.
