Ratha and Thistle-Chaser is a young adult novel, third in the series The Books of the Named by Clare Bell. The series follows a group of sentient, prehistoric large cats called the Named, led by the female cat, Ratha. It also deals with their struggles against the group of non-sentient cats, the Unnamed. On October 18, 2007, it was reprinted by the company Penguin Group.
Ratha, who gave birth to three cats in the first book, Ratha's Creature, had a non-sentient kitten who she named Thistle-chaser with the Unnamed cat she called Bonechewer. Ratha, in a fit of anger with Bonechewer, bit her daughter when she got in the way of her and Bonechewer's fight. This causes Thistle-chaser damage that, due to the lack of therapy, caused one of her legs to shrivel and becomes useless over time. Bonechewer, after witnessing what happened, tells her to leave and she does, regrouping with the Named. After Bonechewer is killed, Ratha has no clue as to where her offspring went.
