Fourth in the Talent/Hive series by Anne McCaffrey, and a re-read.
This one is very much about the continuing adventures of Damia and Afra's children. What Roger and Thian are getting up to with the Navy, and what's happening with Laria on Clarf.
Even though I knew it was coming everything that happens with Roger's 'Dinis still made me cry. Both the initial event and the resolution. The first part wasn't nearly as bad as the first time I read it since this time I knew everything would be ok. But the resolution still gets me.
