Sometimes love takes a second glance in this moving novel about a woman who learns that she is not her parents’ child and must reassemble the fragments of her life.

When bride-to-be Harri Ryan ends up at the ER with a panic attack on her wedding day, her twin brother, George, jokes that she’s the most glamorous patient there. But this is no joke. It's Harri’s second try at the wedding, and when she returns to her Dublin apartment, her fiancé has already packed his belongings. Harri doesn’t want to lose him, but she doesn’t know how to convince him it won’t happen a third time.

George, who knows Harri better than anyone, has a hunch there’s more to the story than cold feet. He confronts their parents, who are acting strangely—as if they’re hiding a secret. And the truth they reluctantly reveal devastates both twins. Now, not only has Harri lost her fiancé, but George’s relationship with his partner begins to fall apart, and both twins have to fight to hold on to those they love and to themselves. As the world they thought they knew crumbles around them, can Harri and George find a way to pick up the pieces before it’s too late?

A rich, multi-textured picture of ordinary people swept up in a scandal they never could have imagined, As Sure as the Sun manages to tickle your funny bone, tug at your heartstrings, and remind you never to give up on love.
