Query: a fast-forward ride!

A life & death struggle to survive the mental illness of manic/depression.Reviewing a memoir about a manic/depressive's story is a challenge. Be forewarned this book is one helluva fast-forward ride!I guarantee during the time it takes you to read A PROPHET OPERATING AT A LOSS, you will not see your life in the same way, & perhaps, never the same way again!For the most part, Zane Bond is coherent & articulate - until you think about what he has written & then you get a whiff of seething synapses & the taste of burnt brain cells.Zane Bond has a way with words & has been considerate of his readers by keeping his paragraphs short, even though the leaps between them sometimes seem like black holes. His chapters range through a forest of memories, philosophies & insights.While I occasionally became lost or overcome, A PROPHET OPERATING AT A LOSS is a remarkable effort that will leave you breathless & thinking!
