How to Navigate Darkness by DW Gibbs.
Described on Amazon thusly:
"A horrific car crash sees a man’s mind and soul tunnelling through the earth's core and appearing on the direct opposite side of the world inside an unsuspecting host. Trying to make sense of it all, he discovers an ability to move from person to person through the medium of touch. His challenge now is to host-hop back to his wife and children half a world away. From cruise ship comics to homeless philosophers, from advertising vigilantes to food critics, all via a prisoner of a cultish church. As he edges closer and closer to his family, we learn more of his past life and of the events leading up to his untimely demise. This is a tale of time travel in the here and now - a transmigratory pilgrimage to the place he desires most. Home."
Only just started it but excellent so far, and very funny.
