Obscura Burning

The world's going to end in fire. and it's all Kyle's fault. Kyle Wolfe's world is about to crash and burn. Just weeks before graduation, a fire kills Kyle's two best friends and leaves him permanently scarred. A fire that Kyle accidentally set the night he cheated on his boyfriend Danny with their female friend, Shira. That same day, a strange new planet, Obscura, appears in the sky. And suddenly Kyle's friends aren't all that dead anymore.
Each time Kyle goes to sleep, he awakens to two different realities. In one, his boyfriend Danny is still alive, but Shira is dead. In the other, it's Shira who's alive. and they're friends with benefits. Bouncing back and forth is taking a toll not only on Kyle, but on the world too, which might perish along with him. Amid the collapse of his parent's marriage and with realities shifting every time he closes his eyes, Kyle must discover how these events relate to Obscura.
and he's the only one who can prevent everything going down in flames.
