Then I Met My Sister by Christine Hurley Deriso
I think the reason I like this cover so much is because it's so unique! There are so many covers out there that are similar to each other but I can safely say I've never seen any other over like this!
The wispy red design surrounding the photography is so delicate and airy, looking as if it's about to vanish. The photography in the center of the heart is not what you would expect either. The only thing I'm not crazy about it the typestyle, size, and placement of the title. I feel like it was added almost as an afterthought (oops almost forgot to put the title, let's just stick it here.)
