Trista Thompson is a bright and focused eight-year-old who loves to understand how things work. She's fascinated by complex systems and spends hours taking apart toys and gadgets, meticulously documenting each step. While she enjoys playing with her siblings, Luna, Violet, Elara, and Jasper, Trista often prefers solitary activities like building elaborate structures with blocks or drawing detailed maps of imaginary worlds. Her organizational skills are evident in everything she does, from keeping her room impeccably tidy to creating color-coded systems for sorting her collection of toy trains. She dreams of one day designing and building her own railway network.
