Quest for Crests — J.E. Bright

Get ready to rock! The seven Digidestined kids and their Digimon companions leave File Island for the Continent of Server in search of elusive Tags and Crests -- which their Digimons need in order to Digivolve to their ultimate level. But they better find them quick, because the rock 'n' roll Digimon, Etemon, is hot on their heels and his Dark Network Concert Crush is about to knock their blue suede shoes off!
