Hope Lauren has read her share of comics. She’s seen supers around her city and even been saved by some on occasion. And she always hoped that she’d be able to join them. With Jack, her grizzled older mentor with secrets that could shake the world, and Pantheon, a new team of heroes, Hope will have to fight against monumental odds to save Oleander City. In a world of action, comedy, tragedy, and adventure, there’s plenty for a new hero to do.*Readers can expect a mostly adventure-themed superhero journey that will include a slice of life, action, and hopefully exciting world-building. It will also contain a slow-burn GL/Yuri plotline, which I'll eventually get to when I feel like it, I guess. This will be a very long story with many arcs*

"Stay with me and I will give you everything your heart desires. For you, my darling, I would part the mountains, split the sea, and cause havoc on Earth just to have you."
