Reserruction in a New World — Sherry Derr-Wille

When Mark found not only his paternal grandmother but also his step-mother and half siblings, he is amazed when they decide to relocate to Resurrection Ranch to work with those dedicated to bringing their vision to fruition. Chris and Peter's families are also involved in the rebuilding what they hope could be one of the top ranches and educational facilities in the country. They are aided by several aliens who have come to add their expertise to the project. All is well until someone tries to sabotage everything they have dreamed of and built.
