Tempted to read Night Blooming and Hotel Transylvania by the reviewers' comments, I was sorely disappointed in these books and the primary character, Saint Germain.
Germain is "supposed" to be a vampire - although it is really hard to tell since the only vampirific tendencies he regularly exhibits are 1) he has a hard time crossing running water, and 2) he has to tuck his native earth into shoes, saddles, and other accoutrements SO THAT HE CAN BE OUT AND ABOUT IN THE SUN.
Come on, I realize vampire characteristics differ - but two things are usually universal 1) vampires drink the blood of the living to continue their existence, and 2) they can be killed by exposure to sun light.
Oddly enough, "Saint" is an excellent title for Germain because he and Mother Theresa could be good friends. Germain travels the earth doing good works. He spends his time helping ladies that he fancies, kings that require advice and counsel, down trodden servants, outcasts of society, and so on. I really don't know why Yarbro bothered to make Germain a vampire - the books would be more interesting if he were a regular person who did these things; because he is supposed to be a vampire, you keep expecting him to do gothic, vampire-like stuff, when he doesn't, he slips into being dull, predictable, and tiresome.
For me, Yarbro's writing style is tedious, vapid, and uninspired. It took me many more days than it should have to read these books because I kept falling asleep. All of the tedium about titles, church minutia, underdeveloped characters, and loose ends ... I was secretly hoping to permanently misplace the books so that I did not have to finish reading them.
I am sorry that this series did not live up to its billing. Since Anne Rice's glory days (I don't count her more recent work to be a part of her stellar past), it is difficult to find engaging vampire fiction. If you are dying to read this series, make certain that you either adjust your expectations about what a vampire is and does or load up on caffeine before you begin.
