I'm pretty meh about dolphins, but they do a nice job of being the telepath-link animals used in this entry of Norton's galaxy-colonising, timetravelly, trying not to be noticed by angry aliens we stole tech from sorta series.Also, there are witches and whoopsie-doo we done went back in time, shit about the history just tryin' to survive.
