"Promising Tomorrows" takes readers on a literal and emotional roller coaster through two intertwined narratives. Stella, a 29-year-old deep space researcher at Intergalactic Park, balances her demanding job with a passion for writing. She tells the story of Codie, a 19-year-old intern working on one of the rollercoasters to compete for a coveted position at the park. Codie's journey is filled with challenges, resilience, and the strength of female friendship. The true question lies in who Stella is really writing about- and how her research on black holes may change everything.
