Picking the right name for your novel.

People seem to have a hard time to spell the name of my second book correctly. I've been sent emails with Celetera, Celleterra, Cileterra, Celetarra, Celeterra, Celletera, Cellettera, Celletterra, Celiterra, Celetirra, Seleterra, Sceleterra, Celaterra, Celederra, Celetterra, Celeterras, and even with St. Erra - For heaven's sake, for once and for all, it's CELETERRA ! C-E-L-E-T-E-R-R-A, it can't be that hard, can it? You can even translate it into Heavenland, if you know a tiny bit of Latin !
