Threshold of the Earth has just released! The first installment of the Trinity of Fire YA trilogy, it follows three 17-year-olds, separated by thousands of miles and unknown to each other, who have little in common besides sharing a birthday, being raised by single mothers, and feeling like they’ve never fit in. Sarcastic Ari, neurodivergent Shui and artistic Peter are beginning their senior years, hoping just to navigate through minefields of bullies, family dramas, overbearing authority figures and complicated love interests. When they start experiencing unexplained phenomena, however, their lives head down unexpected—and paranormal—paths, and they each must investigate a series of mysteries that both reveal startling truths about their identities and even suggest that the fate of humanity might be at stake.
