The Mark of Noba by G.L. Tomas.
Sterling Wayfairer has one goal for his senior year: make his mark. He’s been slipping into the background his whole high school career—distracted by his mother’s mental health, unsettled by the vivid dreams that haunt him at night, and overshadowed by the athletic accomplishments of his popular best friends. But this year is going to be different. He’s going to break a few rules, have some fun, and maybe even work up the nerve to ask his crush out on a date.
But things don’t go exactly as planned. Students are disappearing, Sterling starts losing time, and it all seems to center around Tetra, a girl no one else seems to notice but him. When he finally tracks her down for answers, they aren’t what he expects: He and Tetra hail from a world called Noba, and they’re being hunted by a Naga, a malevolent shapeshifter that’s marked them for destruction.
Tetra and Sterling have distinct abilities that can help them fight back, but their power depends heavily on the strength of their bond, a connection that transcends friendship, transcends romance. Years apart have left their bond weak. Jumpstarting it will require Sterling to open his heart and his mind and put his full trust in the mysterious Tetra.
If he doesn’t, neither of them will survive.
