This should have been a fun side story - the iconic Lestat's tangential side adventure with David Talbot rather than any of the host of vampires which Rice has introduced in the series so far (brilliant). The writing meanders a bit too much but the storyline is entertaining and a blend of predictable and unpredictable. Louis and Claudia make appearances as well. To those ends, this is a refreshing and lighter tale after the intensity & density of Queen of the Damned (which is pure gold).
However, there are 2 big issues that detract from Lestat's adventure. These either did not age well from her initial intent, or somehow Rice thinks her audience will gobble up without question: literal rape, and figurative rape. Lestat is flamboyant and narcissistic but has been depicted thus far with a varying degree of compassion for humanity in general (he feeds only on those who hurt others) and for those he 'loves' (i.e., Gabrielle and Louis). He's entertaining and deviant--all Id and very little Ego, so to speak. But the character here veers so far from that into intentional and enjoyable harm to those who he loves or who don't deserve it. I was troubled for quite awhile after reading the scene where he rapes (literally rapes - she screams 'no') a random waitress while he's human (and it makes even less sense because if it's about desire, he has a consensual relationship with a female later on). Lestat even 'feels bad' and brings her jewelry at the end (so he knows what he did, and uses the term 'rape' several times), but seems to have no concept of the psychological impact of what he's done. I was also troubled (but less so) at the end when he violates David's wishes and turns him, ending his life without his consent (again, David protests and yells 'no'). He also burns Louis's house down, among other things. However, he keeps a nice dog alive so there's that.
In an otherwise lighter and entertaining story, these incidents take Lestat in a somewhat bizarre direction. I wanted to read more about David--her writing is much more lively when discussing David, and he's fascinating. You're also rooting for David & Lestat to hook up (which they don't). But too much focus on Lestat and the rest of the story just doesn't congeal. Maybe it's some attempt at extending the fact that he didn't really have a choice in being turned against his will (?), or saying 'hey Lestat if you were human your actions wouldn't fly' but she took Lestat from flamboyant 'brat prince' to callous and a little bit psychopath. He's more interested in demonstrating his power over people than anything else. I was going to keep reading the series, but I'm not interested anymore. Can't root for Lestat after this.
