M&M Twins - Lost in Browser Cave — Jessica Tornese

Meg and Matt Browser are on a mission. Their home is on the brink of foreclosure and the twins know no other way to save their home than to go on a search for the caves of Browser Territory; the same caves Matt's grandfather told him hold treasures of the past. Navigating the unfamiliar, dark world of the cave is terrifying enough, but when the twins run into treacherous climbs and icy, bone-chilling water, the trek turns from a glorified adventure into a real life game where the stakes could be fame...or death. The twins have to push each other to the limit to escape the clutches of the cave, all in the hopes of finding the infamous Minutemen treasure and saving the only home they've ever known.
