Monsieur Mardi-Gras Descendres Series by Éric Liberge, Thomas Strauss

A fatal slip on the toy car that his son had left in the bathroom, and Victor Tourterelle is dispatched straight to the other side of the mirror, to the beautiful world of chalk desert, under a sky as black as ink. No noise, not a soul. In his new state, Victor finds that he's still fully conscious, more acutely than on earth, even. But his body is only bones. Little does the dead man know that he's at the dawn of the wildest adventure of all time...

The bony masses are gripped with blind panic ever since the new arrival, renamed 'Ash Tuesday', started kicking up a fuss about his post-mortem condition. Ash Tuesday manages to escape during his transfer to Saint-Luc, the adjustment center for twisted spirits. The Militia sends out search parties all over the land to try and track down the dangerous rebel escapee... moreThe bony masses are gripped with blind panic ever since the new arrival, renamed 'Ash Tuesday', started kicking up a fuss about his post-mortem condition.
