Adventuring turned out to be boring. Zach thought back to all the fantasy books he'd read where a team of questers traveled overland, and realized a few things. First he'd pictured himself with a loyal steed that would have done most of the walking, so he hadn't anticipated the blister forming on his left heel or the tiny pebble that seemed to have worked its way under his sock, so that even when he stripped off his sneaker he couldn't find it.He hadn't thought about how hot the sun would be either. When he put together his bunch of provisions, he never thought about bringing sunblock. Aragorn never wore sunblock. Taran never wore sunblock. Percy never wore sunblock. But despite all that precedent for going without, he was pretty sure his nose would be lobster-red the next time he looked in the mirror.He was thirsty, too, something that happened a lot in books, but his dry throat bothered him more than it had ever seemed to bother any character.And, unlike in books where random brigands and monsters jumped out just when things got unbearably dull, there was nothing to fight except for the clouds of gnats, several of which Zach was pretty sure he'd accidentally swallowed.
