It is actually written by Hiermonk Damascene, not Fr. Seraphim, but Hieromonk Damascene is an associate of Fr. Seraphim's (resided in the same monatery in Platina).
I haven't read it yet, but it sounds interesting. It looks too long winded though. I can barely handle 600+ pages of a fantasy novel, let alone something philosophical (J.S. Mills will put me to sleep in 5 pgs). I wish there was a condensed version that was 1/3 the length.
