Patrick at Mysterious Galaxy in San Diego is my connection for good fantasy and good science fiction. This year he got me hooked on military sf, space operas, the kind of novels that span light years as well as decades, where fates of galactic empires hang in the balance and it all comes down to the decisions of one man or woman in the captain’s chair of a space carrier facing impossible odds. The battles rage up and down solar systems and in and out of hyperspace and even if you’re a card-carrying pacifiist you can’t help but thrill to the might and majesty of it all.
In Jack Campbell’s 
Lost Fleet series beginning with Dauntless, a war has been raging between the Syndic and the Alliance for more than a century, and in a perfidious bit of treachery the Syndic has killed the Alliance fleet’s combat officers. Ah, but then the Alliance rescues Captain Black Jack Geary from the cryopod he’s been adrift in ever since the last battle he fought a hundred years before. Since, after they wake him up, he’s the most senior officer in the fleet, he takes command, and over six novels leads the lost Alliance fleet home.
John Scalzi’s Old Man’s War is the direct descendant of Robert A. Heinlein’s Starship Troopers and Joe Haldeman’s The Forever War. At age 75 John Perry leaves earth to join the Colonial Defense Force. In return for a new young body, one specially upgraded for battle, John and his peers will fight the alien races who are in competition with the CDF for new planets to colonize. John’s got a smart mouth and a grunt’s-eye view and he is very good company through a plot that just keeps throwing new stuff at you, and then throws some more. A must read.
Right now I’m tearing through David Weber’s Honor Harrington series like a dreadnought through n-space. Think Horatio Hornblower with Pip for a pet. In On Basilisk Station, the first of this now 12-novel series, Captain Honor Harrington, Royal Manticore Navy, and her ship Fearless are assigned to picket the galactic transfer port Basilisk. Smart, principled, courageous, the aptly-named Honor cleans up the mess left behind by the last captain, including but not limited to a planetary insurrection and an enemy invasion. The characters are great, the plots brobdingnagian, but the detail of the setting is these novels’ greatest strength. You feel like you’re one of Honor’s crew and you will both cheer and cower during the battle scenes.
