"Lira Brannon’s young adult science fiction/fantasy novel, Four Days to Fusion, is an exciting and fast-paced apocalyptic novel. There are no zombies in Four Days to Fusion nor are there nuclear clouds; instead, Brannon has created a mythology based on the planets and the solar system. I was fascinated by the story which takes place on two stages, here on Earth and at the High Court Cluster of the Seven Sisters. Seren is a strong and capable character whose sense of self and world is abruptly shattered in a matter of moments. Brannon’s story is well-plotted and original, and her characters are compelling and authentic. But Seren, the teen whose devotion to and concern for her Betta fish, Glub, remains constant no matter what, is the star of this intriguing and thought-provoking story. I’m looking forward to reading the sequel to this story, Countdown to Combustion. Four Days to Fusion is highly recommended."
