A Moonlit Knight (Ladies of St. Jude's Abbey #3)
Jocelyn Kelley

Summoned in the middle of the night, Mallory must leave the Abbey to protect the Queen's life as a revolt against King Henry rages. With a knight's sense of obligation, she is determined not only to shield Eleanor but to find the enemies threatening her life.
Arriving at St. Jude's Abbey, Saxon Fitz-Juste is amazed by the Queen's choice of a female knight as her newest warrior. A troubadour in Eleanor's royal court, Saxon is ostensibly loyal to Her Majesty - but his true mission remains to be seen.
Although Mallory knows firsthand how dangerous and destructive lust can be, she and Saxon are drawn to each other. But she may soon discover once again how deceit can turn love into hate...
