Katie Wallace had her heart broken once, and she's not going to let it happen again. What's more, she doesn't want it to happen to anyone else if she can help it. After discovering a talent for advice, Katie becomes a unique service provider – a Love Trainer, capable of answering all of the following:

• Should I call him even though he hasn't called me?
• When he turns up drunk in the middle of the night wanting a shag, do I say yes or no?
• Why hasn't he called even though I've texted, left two messages on his mobile and one on his landline?
• Is he worth the effort if I'm not even sure I want to marry him?

But can you really coach a man like you would a dog? Or is Katie about to learn that when it comes to training, the work needs to start much closer to home . . .
