I'd never read Sandra Brown, and, based on "The Switch," won't look to read more.A potentially interesting plot was ruined by ludicrous dialogue, unbelievable characters, and extremely unlikely plot twists (even allowing for the initial premise). And anyone who was surprised by the ending ought to be ashamed.No, wait. That's not true. Readers who thought early on that they had spotted the ending were encouraged to think otherwise by the fact that in several places Brown refers specifically to Melina out of the context of a conversation. E.g. on page 344 a new chapter section begins: Melina repeated to Chief the half of the conversation that he hadn't overheard. Well, it wasn't Melina, we find at the end, so Brown effectively set up a climax, as it were, that made no sense.Too bad. Identical twins can make for interesting reading, but they don't make the grade here.
