So, while I get not wanting to invest in an unfinished series, sales for a second book can be the deciding factor in whether a publisher takes on the third. That might not be a big issue with a writer like Valente, but given the state of genre publishing, one never knows and readers not buying a second book can kill a series and possibly a career. Self publishers also consider previous sales when deciding what books to invest time and energy in. Just something to consider.
