Released February 2011, TGWBAB is a very fun read. It relates the story of Regina Bloomsbury, a teenage musican whose band The Caverns is on the verge of breaking up when the novel begins. When a member of the band very publicly & embarrassingly & definitively does break up the band, Regina makes a wish that she was as famous as The Beatles.
And it comes true. Sort of.
She wakes up in an alternate, wish-world universe where her band The Caverns has replaced The Beatles (though The Monkeys still exist, oddly enough), because, as it turns out, it's impossible to be as famous as The Beatles without being credited with having created their music.
Despite the wish-come-true cliche that the book revolves around, the book avoids, for the most part, feeling too cliched.
Regina is an interesting person to be around, rather than an annoying twit like many of the YA heroines, &, as I mentioned previously, the book is geniunely fun to read.
I was humming a Beatles tune in the shower (which has been happening, nonstop, since I began reading this book) & didn't even know it until my fiance told me it woke him up (whoops).
I highly recommend this book as a frivolous, fun read, for teenagers or for adults.
