She's had it forever. A tiny mark on her hand. No big deal, right? But when Tori discovers that her ordinary freckle is really some kind of microscopic tattoo, she doesn't know what to think, especially after meeting Eric, a guy she feels strangely connected to--and not just because he has a mark too.

All too soon, Tori and Eric realize that atheir marks are only the first clue to a mystery that will change everything. And with each new discovery, Tori finds herself pulled deeper and deeper into a world she could never have imagined.

The Mark by M. R. Bunderson was an entertaining read with engaging characters as well as and engaging story. We follow Tori as she is living and an ordinary teenage life focused on the things most important to her such as school. Thins are going fine until she meets Eric and feel this instant connection that brings her to another world, literally. If things weren’t weird enough she notices the mark on Eric’s hand and how it’s eerily similar to hers. As Tori starts to explore the mark they have she begins to uncover that things aren not what they appear to be even from the people most closest to her. She start to dig deeper and begin to find out who she really is and what the significance of the mark is to her and her newly found friends and what that means for their future because it has been extraordinarily changed.

M. R. Bunderson did a great job capturing my attention and leading me on this crazy adventure with Tori and her friends filled with suspense and danger that had me questioning everything. The romance between Tori and Eric was nice though I wised there was more growth with them growing into their love. It felt that they fell in love and the intensity of that love happen to quickly. I liked how there were different elements of  romance and adventure played off each other creating a good balance within the story. The ending rounded up the story but left clear room for more possibilities and I look forward to reading more about Tori’s adventures and what else is in store for her and her friends.
