Ms. Rowell seems to write on the 'dark' side of this genre. Although I prefer a more light and fun book, her stories are always interesting and normally hold my interest. This story bordered more on the suspense/mystery than the romance. It is one of those stories that either (or both) the H or H have a secret. For some inane reason each refuse to confide it to the other even though it would help solve the mystery. I don't even think this secret when divulged would have solved the mystery more quickly. In fact, the waiting for the "divergence!" was tedious. I started 'skip, skip, skipping'. This hero was in one of the earlier books of this Harlequin series so it was good to see how he fared.
