It took Marc a minute to process what Sol was suggesting, but when it finally clicked, he gave a genuine giggle. "For some people, that might add something to the reading experience," he suggested. "At least, as long as only the reader could smell it, and not everyone." It was the kind of off-the-wall idea that was genuinely quite appealing to Marc, and it would probably work better than chocolates or roses to set a certain kind of mood. "I wonder if you could do something with the properties of amortentia," he mused, more to himself than really to Sol. "You know, how everyone has their own scents that are associated with being in love?" Marc hadn't taken Potions for long enough to experience it himself, but he'd heard about it, and anything personalised always caught his interest.
The changing cover was definitely something that was possible, so Marc nodded. "Yeah, we can make the false cover be anything you want. Or we can set it up so people can enchant it to resemble another book they own. It's more complicated, but it means people are better able to pick something that will fit in at their work, or wherever else they might want to read it. It probably depends who you're aiming to have read it, too. You wanted my opinion, so I guess you want to sell to men as well as women? That means you probably don't want to pick a self-helf book that sounds feminine." Marc wrinkled his nose, because he hated buying in to the attitude that certain things were for certain genders, but he knew from his colleagues that it was important. "I'm lucky, I don't usually have to deal with that kind of thing," he admitted. "Text books are more gender neutral, and the kind of things I make... appeal to the kind of person I am, I guess?"
