Here are the entries for the covers!

By the way, I love all of these. Just because I say more about one cover as opposed to another does not mean I favor it more.

#1 - This cover was designed by pugophie1262! I love that line, and the design-- especially the shattered clocks.

#2 - This one was designed by the fabulous @linhammon-roll-bromance101 on Tumblr. I love this: love the old-timey pocket watch with roman numerals, love the power that seems to be radiating off of it, love the darker color scheme...

#3 - VibishaLakshman designed this one! It's almost reminiscent of Margaret Peterson Haddix's "The Missing" series, at least the redesigned covers... Love it!

#4 - AmberlySunny designed this one and, may I say, my jaw literally dropped when I saw it earlier today. I love the sheer brokenness this one displays with the clocks and such, and I adore the use of one of the shards as a mirror. (The fonts don't hurt, either). This is just... It's amazing.
