Out of the Dawn

Lassair is a 14 year old girl living in the Fens of England at the time when William the Conquerer has died.  She is learning the work of a herbalist and healer from her aunt, all because her grandmother had discovered her dowsing abilities.

Romain de la Flèche and Sibert want her help on a quest that they have in mind.  It means walking to the sea, and where Sibert's family used to live and which Romain's family was given after the Battle of Hastings.  Once there Lassair feels that it is a place of shadow and death.  She also comes to the realisation that Romain is using her and Sibert and they won't be recompensed for helping to find the treasure.

Lassair and Sibert quietly get the treasure, which turns out to be a small crown without Romain knowing.  However, he chases after them, but they escape.  Unfortunately malevolent forces are at work.  Back in their village, Romain's uncle comes in search of them.  They find the crown on Sibert, and charge him with theft, plus the murder of Romain.  Now some way must be found to prove Sibert's innocence.

She is forced to go through an ordeal to prove his innocence, but while she is doing that, the crown is stolen.  What follows is another ordeal for Lassair and Sibert.  Out of the Dawn is a good historical novel.
