Miranda Adams is in desperate need of a milagro-a miracle. She's trying to find her half-sister, Soledad, living in an orphanage somewhere in Mexico City.

A Christian romance.
Very enjoyable christian romance/adventure. Great characters and plot. Lots of twists and turns. Memorable discussions of what christianity and faith are about.
