Author David Feist spins, with his outstanding class of 4th graders from East Tennessee, the funniest tale ever -of all the stresses children go through building up toward their "end of course" tests in the Volunteer State. Feist, a prolific author with 36 titles written in diverse genres, wonders if "Operation Zero Dark Thirty" will bring more laughs than even the spring 2013 release of "The Cook Nearly Killed Us and Other Funny Bones to Make You Cry Laughing!"
