Lord James Warren, Viscount Sudbury, lives a quiet, safe, and predictable life alone on his estate in Suffolk, only traveling to London once a year to visit family and satisfy his more forbidden needs. But this year, his routine is shattered when his niece and nephew ask him to help a beautiful young man they've only just met. Kyle Allen, alone and running from his abusive lover, stirs feelings in James he has long denied for fear of tarnishing his reputation and losing his family's love. Though undeniably drawn to Kyle, James's honor demands he keep that part of himself completely secret, even if Kyle is feeling the attraction as well, despite the pain and betrayal he's recently suffered. Assistance and a future for Kyle might be secured, but then they would face a choice, stay apart and continue leading half-lives, or risk everything for love"--Page 4 of cover.

"In the summer of 1942, twenty-one-year-old Anne Calloway, newly engaged, sets off to serve in the Army Nurse Corps on the Pacific island of Bora-Bora. More exhilarated by the adventure of a lifetime than she ever was by her predictable fianc, ̌ she is drawn to a mysterious soldier named Westry, and their friendship soon blossoms into hues as deep as the hibiscus flowers native to the island. Under the thatched roof of an abandoned beach bungalow, the two share a private world--until they witness a gruesome crime, Westry is suddenly redeployed, and the idyll vanishes into the winds of war. A timeless story of enduring passion, The Bungalow chronicles Anne's determination to discover the truth about the twin losses--of life, and of love--that have haunted her for seventy years"-- I : LAWYER AND CLIENT: Upper and lower limits of representation --

Conclusion : psychopharmacology / William H. Meller, Sarah J. Meller. "Those who are afflicted as well as those who are adversely affected by mental illness often live lives of 'quiet desperation' without recourse to appropriate assistance. Most caregivers confronted with these illnesses in the work of ministry have had no training or accurate information about mental illnesses, so frequently they do nothing, resulting in further harm and damage. Others may operate out of a theological system that does not adequately account for the nature, severity, or treatment of these illnesses. In Ministry with persons with mental illness and their families, eighteen psychiatrists and pastoral theologians come together in an interdisciplinary, collaborative effort to ensure accuracy of information concerning the medical dimensions of mental illness, interpret these illnesses from a faith perspective, and make suggestions relative to effective ministry. Readers will learn how science and a faith tradition can not only coexist but work in tandem to alleviate the pain of the afflicted and affected"--Publisher description. I.
