this is book 1 of 3 of the trilogy In the heart of New York, we have Lilly Bailey and Lexy Carter. Two bipolar women who live almost regular day lives in New York. You could say they are "bipolar" opposite as Lexy is openly lesbian and ruthless but mostly kind with her bipolar type 1. While Lilly is a closeted lesbian suffering from Bipolar type 2 and is really shy.
