I'm looking for a book but I only read the synopsis which goes like this  :

In our society a company pretends that reincarnation is a thing. For a large sum of money they can, after your death, find the new body you inhabit so you can keep the possessions you had in your previous life. The synopsis ended by asking some questions about how this could affect the world we live in. Is this just a hoax ? Can and should the governments do something about that ? If only rich people can now virtually live forever, what will the social repercussions be ?

Thanks for your help !

PS: I'm quite sure I read that in french, if that's any help
