I ran
com.github.babluboy.bookworm foo.epub
and it complained:

[WARNING 22:12:14.238713] bookworm.vala:681: EBook not found at provided location:foo.epub
[FATAL 22:12:14.244095] [GLib-GIO] g_file_query_exists: assertion 'G_IS_FILE(file)' failed

Using an absolute path worked. This is rather surprising behavior.
