Lovely, Dark and Deep by Amy McNamara
I think trees are one of the most beautiful things ever! I pretty much fall in love with every book cover that has a tree on the front. I find this one to be especially beautiful. The intricate tangle of bare branches covered in snow is just breathtaking and really peaceful.
I really like how the title is placed in a simple white rectangle right in the mass of tree branches, it creates a great contrast between the two. Also, the coloring seems quite magical with the pink tint at the top that slowly fades to purple as it goes down.
