In the turbulent summer of 1974, Kate Mularkey has accepted her place at the bottom of the eighth-grade social food chain. Then, to her amazement, the "coolest girl in the world" moves in across the street and wants to be her friend. Tully Hart seems to have it all---beauty, brains, ambition. On the surface they are as opposite as two people can be: Kate, doomed to be forever uncool, with a loving family who mortifies her at every turn. Tully, steeped in glamour and mystery, but with a secret that is destroying her. They make a pact to be best friends forever; by summer's end they've become Tully and Kate. Inseparable. So begins Kristin Hannah's magnificent new novel. Spanning more than three decades and playing out across the ever-changing face of the Pacific Northwest, Firefly Lane is the poignant, powerful story of two women and the friendship that becomes the bulkhead of their lives.
