This is your typical Harlequin Romance: boy meets girl, boy and girl fall in love, boy and girl have a misunderstanding resulting in a spat, through various convolutions they realize it was all a misunderstanding. Throw in a match-maker grandmother and a brother as a rival to make it a little interesting. Stir vigorously. Then boy and girl kiss and make up—or in this case, end up in bed together, with promises of love and marriage, of course. I don't think this is a spoiler. It's the typical plot of a Harlequin Romance, and anyone who reads the things has seen it—over and over again.
Yeah, like a typical Harlequin Romance, it gets sappy toward the end, too.
At one point, I bought a bunch of these things. Heaven only knows what possessed me, but I paid for them so I'm hell-bent to actually read them.
