Linnet

Linnet, a too-trusting upper-class young lady of fourteen, ran away to seek adventure in the heart of sixteenth-century London. Along the way she met Sir Colin Collyngewood, a gentleman, and accepted the ride he so kindly offered her. That was her first mistake. Her second was in accepting his hospitality, although by that time, she had little choice. A fascinating and intriguing book based on an actual historical plot.

Sally Watson wrote a series of historical fiction girls adventures that follow a family lineage from the Elizabethan era through (I think) the 1870s. I was totally addicted to these books when I was a child but Linnet was the only one I managed to own. Since then I have acquired Mistress Malapert - one where the protagonist runs away and joins the Lord Chamberlain's men and Lark - where a young girl runs away from her Puritan Uncle's family to try to join her grandparents with the Jacobites in France.
