When Laura Pratt's long-distance partner of six years tells her "it's over" at a busy downtown train station, she is sent reeling, the breakup coming out of the blue. He, meanwhile, closes himself off, refusing to acknowledge Laura and her requests for explanation.

In the following days, months and then years, Laura struggles to make sense of this sudden ending, alone and filled with questions. A journalist, she seeks to understand the freefall that is heartbreak and how so many before her survived it, drawing on forces across time and form, and uncovers literary, philosophical, scientific and psychological accounts of the mysterious alchemy of how we human beings fall in love in the first place, and why, when it ends, some of us take longer to get over it, or never do. She weaves this background of cultural history with her own bracing story of passionate love and its loss, and offers some hope for arriving--changed, broadened, grateful--on the other side.
