A Light agent's Shadow side rises in Vicki Pettersson's third Signs of the Zodiac novel, The Touch of Twilight.Masquerading as her dead sister, Joanna Archer has several nemeses of varying levels - not everything goes well for a superhero. New danger is always arising, so Jo has a plethora of paranormal problems...as well as the very mortal one of winning back her human lover.I read the first 100 pages a month ago, then broke away to read other things, and picked up where I left off, so my memory for details was scattered. The author has a refreshing vision of urban fantasy, even if Joanna does drive you bananas, and sometimes on a regular basis. I'm now awaiting Zoe Archer to get some long-awaited face-time, but at least here in Book 3 we get more of the awesome Chandra.Problem: I can't find any release dates for Book 4, City of Souls, in Australia or the UK. Our dear spoiled North American friends, however, need only wait until late June.
