Since it's 'shes back with a new mate novel', the main character is likely a female who has returned and is now with a new partner. There could be other supporting characters like her friends or family who might play important roles in the story. For example, her best friend could be either supportive or skeptical of her new relationship, adding more depth to the plot.
I'm not sure as I haven't read the novel yet. But usually, the main character would be the 'she' in the title, and her new mate would also be a significant character.
Without reading the novel, it's hard to say exactly who the main characters are. However, based on the title, the woman who is 'back' and her new mate are central. There may also be antagonists, perhaps an ex - partner who is jealous or someone who doesn't approve of the new relationship. These characters would create conflict and drive the story forward.
