With some exceptions, the promise of the book breaks down in its execution. For the most part, the chapters are review articles written in wooden prose, with little evidence of editing. Not only are there the usual redundancies and inconsistencies between chapters so common to multiauthored works, the quality of the writing leaves much to be desired. Ambiguous references to "these findings," sentences that are more than 70 words long, typographical errors, and inconsistent terminology should not have seen the light of day. "Factorizing," "onsetting," and "prepubertally" would not have passed an editor's pencil. Telling us that treatment of depression is challenging and rewarding does not enlighten. Low on analysis and high on regurgitation of facts, large parts of the book make for slow reading. However, each chapter has a long bibliography, even though there is a lot of chaff in with the wheat. One chapter has 16 pages of text and 11 pages of references. In addition to the poor editing job, the publisher helps makes the book difficult to read by using a type size that seems smaller than what you are reading now. The references are printed in yet smaller type. The reader is confronted with an eyeball-numbing sea of print.
