Sidney Sherman is plunging back into the dating pool, just in time for her 40th birthday. Nothing could possibly go wrong.

Except her job steals most of her energy, her kids are growing up and leaving her, her friends are maybe a little too excited about helping her date, and her social anxiety is at an all time high. Oh, and she hasn't dated in 7 years.

Sidney Sherman's Marshmallow Heart is an emotional rollercoaster through the modern dating scene, with poignant stories, a couple of "what the actual &%*$" moments and a puppy. It might not be perfect, but it's definitely a good time.
