Heechee Rendezvous

I really enjoyed this one, the 3rd installment of the Heechee Saga, quite a bit. Detailing the further adventures of Robinette Broadhead and his wife, but also involving crazed lunatic who grew up as a feral human in a Heechee ship, a former acquaintance of Robin's and his wife, and an old flame from the previous books. And ultimately, there is the titular meeting of the aliens spoken of so frequently but never before met in the series.

While I know there are subsequent installments in the series, I don't know if I'll move on to the next ones as this felt like an entirely satisfying ending to the series. What do you think? Is it worth moving on to the next books?

EDITORIAL REVIEW: “The Heechee are one of the great creations of science fiction.” Jack Williamson. After millennia had passed, Mankind discovered the Heechee legacy (an alien culture that fled to the reative safety of a black hole)–in particular an asteroid stocked with autonavigating spacecraft. Robinette Broadhead, who had led the expedition that unlocked the many secrets of Heechee technology, is now forced once more to make a perilous voyage into space–where the Heechee are waiting. And this time the future of Man is at stake.... THE HEECHEE SAGA Book One:GATEWAY - Book Two:BEYOND THE BLUE EVENT HORIZON - Book Three:HEECHEE RENDEZVOUS - Book Four:THE ANNALS OF THE HEECHEE
