Ship of Fire — Michael Cadnum

A young Englishman embarks on history's most daring naval assault

Thomas Spyre wields his rapier like an expert, but his blade has never drawn blood. A surgeon's apprentice in Elizabethan London, young Thomas spends his days learning the most modern medical techniques -- from amputation to bloodletting -- and by night he tries to keep his master from gambling away their earnings at bear fights. When a bad bet leaves their purse emptier than ever before, Thomas fears they are destined for the poorhouse. But a strange stroke of luck is about to whisk them away from England toward one of the greatest adventures of all time.
 
Thomas and his master are called upon by Sir Francis Drake, the legendary swashbuckler, to accompany him on a daring raid of the Spanish port of Cadiz. As a surgeon aboard the ship, Thomas will have to learn the nature of manhood, medicine, battle, and espionage -- all while the cannons fire.
