Catherine 'Chess' Clovis is a supporting character in Soulmate. She is a teenage human girl and Hannah Snow 's best friend.
It's heavily implied that Chess, like Hannah, is an Old Soul who has been reincarnated as Hannah's companion in at least three of her lives. Chess is described as being "petite and pretty", with short dark hair and green, slanted eyes that are "cat-like". She is said to look "faintly exotic". Chess is said to be "smart" and "savvy". She appears to be a cheerful, compassionate girl and clearly cares deeply for her best friend Hannah, expressing concern for her on a number of occasions, supporting her and offering her assistance in getting to Las Vegas with few questions asked, also showing she has a great deal of trust in Hannah.
In her earliest known incarnation, Chess was named Ket and was born in the Stone Age. She was a member of the Tribe of the Three Rivers and was best friends with Hannah, then known as Hana. Ket expressed romantic interest in a boy named Ran and mentioned that he wanted to 'mate' her. She seemed interested in accepting his offer and asked if Hana had found anyone to mate yet. Ket was present when Theorn was found and captured after drinking Ryl's blood.
She seemed to feel sorry for him, but was also somewhat frightened of him. It is unknown if Ket survived Theorn's later massacre against the tribe. Ket was later reincarnated as an Egyptian girl named Khet-hetepes. Along with Hana - who was now called Ha-nahkt - she served as a priestess of the goddess Isis. Not much is known about Khet-hetepes' life in Ancient Egypt - Ha-nahkt describes her being her friend and considers running to get her when she encounters Maya for the first time due to her mistrust of the woman.
It is not mentioned if Chess was reincarnated into any of Hana's other lives, though it can be assumed she was. In the late 20th century, Chess was reincarnated as Catherine Clovis, or Chess for short. She lived with her mother in the town of Medicine Rock, Montana. Chess again befriended Hana, now known as Hannah Snow.
