About the author

Ariel Sullivan lives in Connecticut with her husband and two sons, as well as their two French bulldogs. Growing up a military brat, Ariel moved every two years and was a perpetual new kid; she often observed from the outskirts, where a deep love of reading was born.

When she isn’t writing, Ariel loves to read everything from poetry to psychology, bake with her sons, listen to live music and travel.
