The luck of Brin's five

A human man crashes on a different planet & is rescued by Brin's clan, because their old Luck died and they need a new one. If you like books about strange (or alien) cultures where you have to figure things out as you go instead of having them explained to you, you might like this book. I did. ;) As an anthropological sidenote, it is the most emic book I can remember ever reading.
