Catherine was an early riser, a poor sleeper; none of this was unfamiliar to her. But she was seeing through new eyes this morning. She unclenched her hand. Fighting her addictions had taught her about their power, and she knew she was clinging to an unhealthy memory. But right now it felt good, and she could only hope those shocks of excitement weren’t visible to the others.
