A Dance with Dragons
Along with the rest of House Ryswell, Roose attends the wedding of Ramsay to "Arya Stark" (actually Jeyne Poole) in Winterfell. Lord Roose Bolton mentions to Theon Greyjoy that Roose Ryswell is his namesake.
- The appendices of A Feast for Crows and A Dance with Dragons list Roger, Rickard, and Roose as Rodrik's quarrelsome cousins, but the text of A Dance with Dragons specifies them as his sons in 20. Reek II and 32. Reek III.
