True love lasts forever... Which is fortunate for Hope Delafield, since she's had true love nailed since she was thirteen. Going out with the hot boy next door has outlasted school, university, and even a move to London. So at twenty-six, Hope feels that she and Jack - officially pre-engaged, and generally more sorted than all their friends put together - are guaranteed to live happily ever after. Until, that is, Hope catches Jack kissing her sexy best friend Susie. Jack swears it's a drunken mistake, and Hope sort-of believes him, even though Susie's pretentious, annoying ex Wilson thinks she's crazy to do so. Should she kick Jack to the kerb, throwing half her life away, not to mention the future she has planned? Or should they try and work it out? Staying together seems to be the right answer, and Hope's getting to grips with her new role of Forgiving Girlfriend, when the unthinkable happens: she gets up close and personal with irresistible temptation herself...
