Rainbow Rowell is quickly becoming the new John Green, the patron saint of young adult readers. She’s had such hits as "Eleanor and Park," "Fangirl," "Landline," and "Attachments."

While she is most known for "Eleanor and Park," "Fangirl" was always my favorite of her books. In "Fangirl," Cath heads off to college and has to come to grips with the fan-fiction she is obsessed with writing. That fan-fiction, Carry On Simon Snow, is a central part of the main story, but we don’t get too much of a glimpse into the World of Mages that Simon Snow inhabits.

"Carry On," Rowell’s latest book, is our chance to go into the World of Mages. I normally like Rainbow Rowell’s books, I do, but I was less than impressed with "Carry On." Perhaps that is because I’ve already read and loved "Harry Potter." Yeah, "Carry On" is basically fan-fiction of "Harry Potter" fan-fiction.

There are some differences, for copyright reasons, but it is so similar to "Harry Potter" that I almost couldn’t bear it.

Simon Snow is The Chosen One, the most powerful magician the World of Mages has ever seen. He’s an orphan, of course, because what savior isn’t? His “father-figure” or rather, his Dumbledore is The Mage, the Headmaster of Watford, the knock-off Hogwarts. The great villain of the story, the Insidious Humdrum, is a form of Simon Snow himself, reminiscent of young Tom Riddle, and the final scene of "Carry On" comes with its own anticlimactic climactic battle between good and evil that "Deathly Hallows" teased us with.

Instead of Hermione, we have Penelope, aka Penny, Simon Snow’s better half, who is the brightest little witch of her time, and would surely rack up all the house points at Hogwarts. She’s always the brain of the operations, the smart one, and we all know she’s the real hero, just like Hermione.

"Carry On" is basically Harry Potter if Draco was in love with Harry. Don’t think about that too much. It’s pretty odd in either case, and it comes out of nowhere in "Carry On" like it would if it was suddenly inserted into "Deathly Hallows."

It’s a compelling book. You want to keep reading, and reading, and reading, and you can’t put it down until you’re finished. But at the end, it is pretty underwhelming, and you wish you had just reread "Harry Potter."

Rainbow Rowell is a great writer, I love her, but JK Rowling did it better.
