How to reach host behind site-to-site VPN connection through peering VPC connection

I actually have following situation:

I successfully reach host C from Host A using VPN static routes. I need now to reach it from host B. I thought to create a route table from VPC B that forward request with ip/32 of host C through Peering connection... But it doesn't work.

There is a way to do that?

N.B. I cannot use Transit Gateway

Thanks!

I need now to reach it from host B.

You can't do this. VPC peering is not transitive. You can setup VPC connection to VPC B as well instead.
