Rosie Ainsley and William Thatcher have been best friends for as long as they can remember, serving under Sir Ector alongside their lifelong friends, Roland and Wat. When Sir Ector unexpectedly dies during a joust, William seizes the opportunity to pursue his lifelong dream of becoming a knight, assuming his master's identity and entering the lists as Sir Ulrich von Liechtenstein.
With Rosie, Roland, and Wat by his side, William embarks on a new life of jousting, adventure, and unexpected friendships-including the famous writer Geoffrey Chaucer and a fiercely independent female blacksmith named Kate.
But while William is chasing his dream of knighthood, Rosie has been quietly holding onto a dream of her own: a life with William.
Before she can confess her feelings, however, William's attention is captured by the beautiful noblewoman Jocelyn. As his infatuation with her grows, Rosie is left wondering if the man she's loved for years was ever truly meant to be hers-or if it's finally time to let him go.
