"Griffin and Sabine" is an exceptional series of books as it is filled with postcards, envelopes and letters, and extraordinary artwork by Nick Bantock. This book is simply a back-and-forth conversation through postcards and letters about two people who met each other in the weirdest way. This is defenitely an interesting book to read. Think about it - opening up someone else's envelopes and reading letters.
"Sabine's notebook" is the continuation of Griffin and Sabine's mind-altering postcard/letter exchange, where Sabine finally decides to go meet Griffin. I won't say more because i don't want to ruin anything,
"The golden mean" concludes Griffin and Sabine's mind-altering postcard-letter exchange. I'm not going to say anything about it since i would *really* be ruining it for you. Well, the good thing is that once i finished the series i felt like having a pen-pal (hehheh) but the bad part is that the ending is kinda, well, sad and frustrating and it's... well, i wish *that* didn't happen. It was unexpecting and i was left not knowing what to say or think. P.S. I found out that there is actually another book that came out, 8 years later, called the rediscovery of, i dunno what. I have to read it!!!!! I must!!!
