Tom believes, even in this cynical modern world, in the notion of a transforming, cosmically destined, lightning-strikes-once kind of love. Summer doesn't. Not at all. But that doesn't stop Tom from going after her, again and again, like a modern Don Quixote, with all his might and courage. Suddenly, Tom is in love not just with a lovely, witty, intelligent woman -- but with the very idea of Summer, the very idea of a love that still has the power to shock the heart and stop the world. The fuse is lit on Day 1 when Tom, a would-be architect turned sappy greeting card writer, encounters Summer, his boss's breezy, beautiful new secretary, fresh off the plane from Michigan. Though seemingly out of his league, Tom soon discovers he shares plenty in common with Summer. By Day 31, things are moving ahead, albeit "casually." By Day 32, Tom is irreparably smitten, living in a giddy, fantastical world of Summer on his mind. By Day 185, things are in serious limbo -- but not without hope. And as the story winds backwards and forwards through Tom and Summer's on-again, off-again, sometimes blissful, often tumultuous dalliance -- all of which adds up to a kaleidoscopic portrait of why, and how, we still struggle so laughably, cringingly hard to make sense of love and to hopefully make it real.
