From the back cover:
With over three million copies sold, the Griffin & Sabine novels are beloved around the world for their artful fusion of captivating storytelling, lush illustration, and fascinating correspondence. At last, best-selling author Nick Bantock brings us a new volume in the Griffin & Sabine story—a tale rich in the artistry, mystery, and surprise that makes the original saga so beloved. As the remarkable fates of Griffin and Sabine are gradually revealed, we are introduced to Matthew and Isabella, long-distance lovers who find themselves entwined not only in each other’s lives, but also in a perilous and alluring intrigue.
First off, I don’t recommend buying these books simply because they’re very costly. They’re about $20 each because of all those aforementioned lush illustrations, but can be read in about the same amount of time as a graphic novel but with less overall content. If you’re lucky like me, your library will have them and the patrons will have been conscientious and not messed any of the letters up. (You can actually slip these out of envelopes and unfold them and stuff.)
This is the first book of the second trilogy regarding the correspondence of Griffin and Sabine. The line up there about their fates being revealed is not true at all. They’re still as murky as ever. And now more murk has been introduced with Matthew and Isabella, who I think are both actually real, but I’m not sure. There are lots of debates regarding these novels as to whether Sabine’s real or if Griffin’s just insane. I definitely tend toward the latter camp, but would like some confirmation. Alas, I don’t think I’m going to get any.
These books are like poetry. Lots of postcards with weird art and letters with cryptic hints that’re probably symbolic but which I often don’t fathom and can’t really be bothered to try too hard to interpret. Still, they’re pretty interesting and not any serious investment of time. Just don’t fork out $120 for the whole set because you’ll regret it.
