Thanks to everyone for all the help!
I can ask these cards a question about a relationship that I'm worried might be rocky, and I'll pull a card about contentment and serenity in the present. That is absolutely false--if anything, I'm not serene right now. I'll reshuffle and ask again (which I know shouldn't be done; when I do this with other decks, I usually end up pulling the same cards, or at least the same meaning) and pull "negative" cards where "positive" ones were, and vice versa. It's hard to explain, but, unlike with other decks, I can't shake the feeling that I'm simply pulling cards at random.
I usually read by intuition, but I've found that with this one I'm often consulting the "little book" to check my work. As beautiful as the artwork is, I just don't think I'm connecting with it.
I'll take your tips to heart and keep trying for a while longer. I love the deck, it's absolutely beautiful, but, right now, that synapse just isn't getting leaped.
