The Quivera Trail — Celia Hayes

The Quivera Trail is intended as a sequel to the Adelsverein Trilogy,
 following the second generation and Dolph Becker courting and marrying Isobel Lindsay-Groves. Desperate to marry, Isobel and her personal maid, Jane Goodacre embark at Southampton for a new life in a new land -- a place entirely alien, when compared to the gentle hills and established estates of England. Slowly but surely, the two women begin exploring their new country ... and what they themselves are capable of achieving.

Dolph Becker's uncle Hansi Richter, the 'cattle baron' as he is now called, has plans for Dolph and Isobel to establish a new ranch near the Palo Duro, in the
Panhandle region. Once the winter refuge of the Comanche, the Palo Duro
is now open to ranchers and settlers like their neighbor, Charles Goodnight. Dolph and Hansi Richter have an English investor for this new  property - but after a long-trail drive to get there and the labor of establishing it from the ground , they discover that not all dangers of the frontier are banished. The Becker and Richter families are soon embroiled in a vendetta with a vicious rustler gang.

Jane, meanwhile, finds a new outlet in teaching school - and a romantic attraction to Dolph Becker's artist brother, Sam. She makes friends with Lizzie Johnson, school-teacher and cattle baroness in her own right, and with the formidable matriarch of the family, Magda Vogel Becker. Can  the friendship between Isobel and Jane remain unbroken in the face of these new possibilities?
