This set of look-alikes I found completely by chance. I was sorting through books at a book sale and spotted The Third Angel, which just so happened to have an image I knew very well—the same picture I'd seen dozens of times on my iPod, on the cover of Secondhand Serenade's album. (You might know Fall For You by Secondhand Serenade, which was pretty popular about a year ago.)
Do you guys like the coloring on the album better than the book, too? The Third Angel's cover is a little too technicolor for me. But I like how you can see the strand of lights on the book cover, whereas, on the album, the strand is just kind of a background thing.
So this is probably one of the stranger look-alike sets I've found: a book to an album; but it's not the only book I've seen that's crossed images with something strange. Stay tuned!
