Parallelogram Boxed Set (Parallelogram Quartet, Books 1-4)

Get all four books in the Parallelogram Quartet—all in one boxed set!

High school senior and amateur physicist Audie Masters has discovered what no other physicist has been able to prove: that parallel universes do exist, and there is a way to journey into them. She also discovers something else: a parallel version of herself, living the kind of life Audie never could have imagined for herself.

Now Audie is living that life, too, full of adventure, romance, and reality-bending science. It’s all more than she could have hoped for—until something goes wrong.

Read the exciting 4-part series all in one boxed set. Time travel, parallel universes, quantum physics, mind-bending science... you'll never look at the universe or your own life the same way again.
