Todd Klein, comics superstar and letterer of (among many, many other things) Top Ten, has reviewed T-Minus: the Race to the Moon on his blog! Thanks Todd! A quotation:
Ottaviani and the Cannons make excellent use of the comics format to tell this complex story in interesting ways. (...) Parts of the story are told simultaneously through the clever use of large panels and small panels on the same pages, each telling a different narrative.
