Don't touch it! It might just get you. Don't open that new book now. Dinner will burn, your children will whine and fuss at being neglected. Not even a taste of the new worlds, new friends. Your real life will slip away, ephemeral as mist and you will forget what is real and what is not.
But your fingers twitch, your soul reaches out, you have to know what is in it. Soon you're ten pages in, fifty, a hundred. You don't sleep, you don't eat, and before you know it, you finish. The words stop, leaving you disoriented and still wanting more.
