As though I could pick just one! I have favorite books for every season, every mood, every setting. For instance, I love (re)reading Outlander by Diana Gabaldon when I'm traveling, and LaVyrle Spencer's Morning Glory gets pulled off my shelves every June. Other favorite reads include:
The Winter King by C.L. Wilson,
Eyes of Silver, Eyes of Gold by Ellen O'Connell.
Romancing Mr. Bridgerton by Julia Quinn.
Ravishing the Heiress by Sherry Thomas.
Undecided by Julianna Keyes.
Dark Horse by Michelle Deiner.
Kiss an Angel by Susan Elizabeth Phillips.
Sea Swept by Nora Roberts.
A Company of Swans by Eva Ibbotson.
Slave to Sensation by Nalini Singh.
Blue-Eyed Devil by Lisa Kleypas.
