A humorous picture book about the adventures of a light bulb who embarks on an enlightening journey, from the acclaimed author-illustrator of Petra. At the end of the hall, near the staircase, is a closet. In that closet lives Ray, who is a light bulb. Ray spends most of his time in darkness, which is pretty boring if you don't know how to fill it. So boring that Ray usually slips into a dreamless sleep . . . Everything changes one day when Ray is migrated into a portable lantern and taken on the trip of a lifetime.

Kirkus Reviews Best Children's Book Here is the riveting dual biography of two little-known but extraordinary African-American Union soldiers in Civil War history—George E. Stephens and James Henry Gooding. Stephens and Gooding not only served in the Massachusetts 54th Infantry, the well-known black regiment, but were also war correspondents who published eyewitness reports of the battlefields. Their dispatches told the truth of their lives at camp, their intense training, and the dangers and tragedies on the battlefield. Like the other thousands of black soldiers in the regiment, they not only fought against the Confederacy and the inhumanity of slavery, but also against injustice in their own army. The regiment’s protest against unfair pay resulted in America’s first major civil rights victory—equal pay for African American soldiers. This fresh perspective on the Civil War includes an author’s note, timeline, bibliography, index and source notes.

Ray Charles: Man and Music is a complete biography of this seminal singer/pianist who has been active on the American music scene since the mid-'50s. Originally published in 1995 by Penguin Books, and universally hailed as the definitive biography, this new edition will bring Charles's life up to date, covering the last 7 years of his life.There are only a few legendary singers who have developed mass audiences while pursuing their own artistic visions: Sinatra is one; Ella Fitzgerald another. Ray Charles undoubtedly belongs in this pantheon of major musical stars. Ray Charles: Man and Music begins with Charles's impoverished childhood in Greenville, Florida, where tragedy struck early when the young Charles went blind at age 6 and was orphaned at age 14. Driven by his enormous talent and determination, Charles landed work playing some of the toughest juke joints in the state, fought heroin addiction, and finally landed a recording contract with Atlantic Records. Unlike other R&B singers, Charles took control of his career from its earliest days, moving on from his gospel-soul stylings of the mid-'50s to break through musical barriers, recording two country albums in the late '50s (at a time when the black presence in country music was barely felt), pure jazz, and then the powerful pop hits of the '60s. Famed music journalist Michael Lydon - a founding editor of Rolling Stone - is uniquely qualified to document Charles's career, having interviewed Charles and followed the star's performances since the 1960s. Originally published in 1995, and universally hailed as the definitive biography, this new edition brings Charles's life up to date, covering the last 7 years of his life. It coincides with the release of a made-for-TV movie starring Jamie Fox as Charles, currently in production by Taylor Hackford. Charles has also issued a new CD recently and remains active as a touring artist throughout the world.

As much as any individual, Ray Bradbury brought science fiction's ideas into the mainstream. Yet he transcended the genre in both form and popularity, using its trappings to explore timely social concerns and the kaleidoscope of human experience while in the process becoming one of America's most beloved authors. David Seed follows Bradbury's long career from the early short story masterpieces through his work in a wide variety of broadcast and film genres to the influential cultural commentary he spread via essays, speeches, and interviews. Mining Bradbury's classics and hard-to-find archival, literary, and cultural materials, Seed analyzes how the author's views on technology, authoritarianism, and censorship affected his art; how his Midwest of dream and dread brought his work to life; and the ways film and television influenced his creative process and visually-oriented prose style. The result is a passionate statement on Bradbury's status as an essential literary writer deserving of a place in the cultural history of his time.

Since their discovery was first announced in 1973, gamma-ray bursts (GRBs) have been among the most fascination objects in the universe. While the initial mystery has gone, the fascination continues, sustained by the close connection linking GRBs with some of the most fundamental topics in modern astrophysics and cosmology. Both authors have been active in GRB observations for over two decades and have produced an outstanding account on both the history and the perspectives of GRB research.
