Earthshine (The Multiverse Diaries)

A magical yoga class inspires troubled college student Em Verde to visit India in search of a teacher. She hopes he can help make sense of her weird dreams, but instead he awakens a powerful ability within her.

Em can access alternate realities. She visits a world where she's living her best life: she's dating her college crush while her geeky gay best friend is a famous athlete. But as the barriers between alternate realities begin to break down, malevolent creatures from a demon realm are unleashed.

Now a secret government agency is hunting them and Em finds herself caught in the middle of a battle she doesn't fully understand. She has to master her abilities quickly before her friends get lost in the multiverse forever.
