Question: How many other books did Sphere Books release the year it released The Intrepid Enchanter? Passage 1:The Complete Compleat Enchanter is an omnibus collection of five fantasy stories by Ametican authors L. Sprague de Camp and Fletcher Pratt, gathering material previously published in three volumes as The Incomplete Enchanter (1941), The Castle of Iron (1950), and Wall of Serpents (1960), and represents an expansion of the earlier omnibus The Compleat Enchanter, which contained only the material in the first two volumes. The expanded version also differs from the previous omnibus by omitting its afterword, de Camp's essay "Fletcher and I". The omnibus is the first edition of the authors' Harold Shea series to be complete in one volume. It has appeared under three different titles. It was first published in the UK in paperback by Sphere Books in 1988 under the title The Intrepid Enchanter and with a foreword by Catherine Crook de Camp. The first US edition appeared under the title The Complete Compleat Enchanter, and replaces the foreword with a preface by David Drake. That edition was published by Baen Books in 1989, and has been reprinted a number of times since. Orion Books published an edition in the UK under the title The Compleat Enchanter in 2000 as volume 10 of their Fantasy Masterworks series. The stories in the collection were originally published in magazine form in the May 1940, August 1940 and April 1941 issues of Unknown, the June 1953 issue of Beyond Fantasy, and the October 1954 issue of Fantasy.
 Passage 2:A native of Miami, Florida, Joyner originally attended Southwest Miami High School, where he played three seasons on the varsity football team at linebacker and defensive back as well as wide receiver and kick returner. As a sophomore, he had more than 100 tackles and also accounted for more than 1,000 yards on offense. In his junior year, he recorded 112 tackles, four sacks and an interception. He then decided to transfer to St. Thomas Aquinas High School in Fort Lauderdale, Florida, a private school and football powerhouse coached by George Smith. Featuring talented running backs Giovani Bernard and James White, St. Thomas Aquinas went undefeated through the season, extending a win-streak that began in 2007 to 37 wins, until losing 28–20 to Manatee High School in a Class 5A state semifinal at Hawkins Stadium in Bradenton, Florida. For the season, Joyner contributed as a shut-down cornerback, recording only 14 tackles (12 solo) as opponents stayed away from his side of the field. He also starred on special teams, as he averaged 39.6 yards per return and managed to return three kickoffs for scores. On offense, he recorded 1,090 all-purpose yards on just 79 touches, scoring four rushing and four receiving touchdowns. His impact on the defensive side, however, earned him the National Defensive Player of the Year award by USA Today.
 Passage 3:He received his initial education in the so-called Palace Secondary School, which Ferdinand had created in 1908 solely for his sons. Later, Boris graduated from the Military School in Sofia, then took part in the Balkan Wars. During the First World War, he served as liaison officer of the General Staff of the Bulgarian Army on the Macedonian front. In 1916, he was promoted to colonel and attached again as liaison officer to Army Group Mackensen and the Bulgarian Third Army for the operations against Romania. Boris worked hard to smooth the sometimes difficult relations between Field Marshal Mackensen and Lieutenant General Stefan Toshev, the commander of the Third Army. Through his courage and personal example, he earned the respect of the troops and the senior Bulgarian and German commanders, even that of the Generalquartiermeister of the German Army, Erich Ludendorff, who preferred dealing personally with Boris and described him as excellently trained, a thoroughly soldierly person and mature beyond his years. In 1918, Boris was made a major general.
