Crystal Christmas — Michelle L. Levigne

Sequel to MUSIC IN THE NIGHT, from Guardians of the Time Stream Christmas approaches, despite illness sweeping through 1870s Cleveland. Carmen, Brogan and the underground community struggle to protect the orphans and destitute who shelter with them, and find ways to celebrate, despite the dangers. Hidden Mountain becomes a haven and a source of miracles, far from the blizzards and dropping temperatures. Brogan and Carmen help Ransom prepare a special gift for Ess: a crystal ring, and a proposal. Carmen is happy for her childhood friend, but she can't help wishing Brogan would make a crystal ring for her, too.
