Olu Brown and his Impact Lead Team are building a church in the fast track and provide encouragement for you to do the same in your context. Zero to 80 is a quick, timely read for church leaders seeking new strategies for innovative and more effective ministry. Hailed by many as the new church start in the U.S. to watch, Impact Church in Atlanta had over 1,000 people participating in worship and more than 400 people in small groups a year after it launched. Zero to 80 provides eighty practical ideas from their wild ride in the areas of vision & design, relationship building, marketing, small groups, hospitality, worship, logistics, human resource development and effectiveness for the long haul. Apply these ideas to create and accelerate momentum for your new church start or growth of an existing ministry.

For fans of 13 Reasons Why and Girl in Pieces, this is a novel that shows the path to hope and life for a girl with mental illness. Seventeen-year-old Catherine Pulaski knows Zero is coming for her. Zero, the devastating depression born of Catherine’s bipolar disorder, almost triumphed once; that was her first suicide attempt. And so, in an old ballet-shoe box, Catherine stockpiles medications, preparing to take her own life before Zero can inflict his living death on her again. Before she goes, though, she starts a short bucket list. This bucket list, combined with the support of her family, new friends, and a new course of treatment, begins to ease Catherine’s sense of isolation. The problem is, her plan is already in place, and has been for so long that she might not be able to see a future beyond it. This is a story of loss and grief and hope, and how some of the many shapes of love—maternal, romantic, and platonic—affect a young woman’s struggle with mental illness and the stigma of treatment.

This book gives a thorough introduction to both regular and singular perturbation methods for algebraic and differential equations.
