Nine Uses for an Ex-Boyfriend

Hope Delafield hasn't always had an easy life.
She has red hair and a temper to match, as her mother is constantly reminding her. She can't wear heels, is terrified of heights and being a primary school teacher isn't exactly the job she dreamed of doing, especially when her class are stuck on the two times table.
At least Hope has Jack, and Jack is the God of boyfriends. He's sweet, kind, funny, has a killer smile, a cool job on a fashion magazine and he's pretty (but in a manly way). Hope knew that Jack was The One ever since their first kiss after the Youth Club Disco and thirteen years later, they're still totally in love. Totally. They're even officially pre-engaged. And then Hope catches Jack kissing her best friend Susie...
Does true love forgive and forget? Or does it get mad... and get even?
