Anthony took the books he himself happened to be holding and returned to his sofa as well, all but flopping onto the cushion and settling in to read each and every single one. Perhaps not cover to cover as he had the first time, but he didn't want to leave the answer to chance, and so he had to pay a good deal of attention.
Having Justin's help on it was pretty good, too. At least in the aspect of getting some things done. He know the other man claimed not to be as good with potions and charms and the like, but Anthony was sure that even just reading on the subject, he'd be able to recognise something of use.
