(4) 4-6 Copernicus Legacy series. Illustrated by Bill Perkins. Wade, Darrell, Becca, and Lily--Guardians of Copernicus's time machine--search for its fifth relic, pitted against Galina Krause and her evil Teutonic Order; and against vengeful Ugo Drangheta, a newcomer to the hunt. Da Vinci references abound, as do car chases and shootouts, riddles and ciphers. Lily's parents' possible divorce adds emotional turmoil. This installment feels overlong, but diehard fans won't mind.

(4) 4-6 Copernicus Legacy series. Illustrated by Bill Perkins. Wade, Darrell, Lily, and Becca continue their international quest to find all twelve relics for Copernicus's eternity machine. This time the stakes are even higher: Darrell's mom (Wade's stepmom) has been kidnapped by the nefarious Teutonic Order, who are also hunting for Copernicus's artifacts. Chase scenes, vivid secondary characters, and codes and riddles make for a stimulating, if credibility-straining and lengthy, mystery.
