As well reported at Jacket Knack, silhouettes are a cover trend on the rise. The following pair of covers both sport silhouettes, but with a couple additional elements that strengthen the correlation. Let’s take a look at the first cover:

Marcelo in the Real World by Francisco X. Stork.

And now, the counterpart:

The Spiderwick Chronicles: The Completely Fantastical Edition by Holly Black & Toni DiTerlizzi.

Side by side:

The low title, nighttime setting, the trees, and the lights (which are stars on the Marcello cover, but faeries (I’m assuming) on Spiderwick) give these two a similar feel, don’t you think?
