This interesting sci-fi/fantasy takes a Robert Altman approach in connecting characters and wondering what they'd do to achieve or avoid happiness. Mild-mannered single mom Pearl works for Apricity, which owns and operates a machine that can determine one's happiness needs all via a simple swab of the cheek. Pearl is good at her job, but she's got a teenage son reveling in his own misery and battles with an eating disorder.

The characters all connect and each of their stories ultimately links with another. I already find myself wanting to read this one again.
