As the Thirteen realize the Book Worms might be the answer to finding their mates, the unmated members go to protect the women who now have targets on their backs.

For Darragh Curran, the whole situation is bittersweet. Dar's brothers, The Thirteen, mean everything to him and he's grateful a few have finally found their mates, but now duty forces him to leave the man he loves behind and open himself to the woman who Fate says is his future.

Riordan Whelan hasn't been alone since the day he met Darragh when they were boys. It was a friendship that grew into love. After Darragh was selected for the Thirteen, Ri ignored the future without his Bear and lived in the moment. Then the day arrived and Darragh kissed him one final time before leaving for Ireland. Riordan knew the Dásreach had to come first but he wasn't ready to let go of the male he loved, so he jumped at the chance to follow him.

Amelia always put on a brave face, even as her eyesight degenerated and the life she'd known growing up slowly faded away. Reading, and later listening to, books was her escape and the Book Worms became her rocks. At her age, women typically had a boyfriend... not her. It was easier to dibs a book boyfriend than to find a real-life breathing one.
