Dan is (not) dead

Dan wakes up as a ghost in a strange forest, and doesn't remember anything. They soon meet Lazare, who explains that they're in a place called the Whisperground, and that they can come back to the Living realm. They just have to allow them to help them recover their memory. However, both of them seems to be hiding things from the other, and time's running out... (CW : this comic tackles heavy topics such as mental health issues and suicide.
