My Very Unfairytale Life, by Anna Staniszewski debuted on November 1st. This book looks like so much fun!
Here's an excerpt from Goodreads:
"You know all those stories that claim fairies cry sparkle tears and elves travel by rainbow? They're lies. All lies."—Twelve-year-old Jenny has spent the last two years as an adventurer helping magical kingdoms around the universe. But it's a thankless job, leaving her no time for school or friends. She'd almost rather take a math test than rescue yet another magical creature! When Jenny is sent on yet another mission, she has a tough choice to make: quit and have her normal life back, or fulfill her promise and go into a battle she doesn't think she can win.
