If Robert and Bryan could specialize in any material, it would be book reviews! Check out their review of The Paper Magician by Charlie N. Holmberg. 

Ceony Twill was the top of her class at the Tagis Praff School for the Magically Inclined, but even that doesn't mean she can choose her fate. While most students get to choose their material specialty, she's stuck with paper and the eccentric Emery Thane will be her guide. After she forever bonds to paper as her specialty, her master is attacked by a practitioner of dark, flesh magic. Now she must use everything she's learned to keep Emery Thane alive in a journey that will take her into the chambers of Thane's still-beating heart, his mind, and his soul.
