I am thinking of reading the Arrowverse spinnof novel. I have two questions about them. First, are they canon, are they part of the main continuity of the four shows? I would also like to know the same for the spinnof comics, are they canon? Second, if anyone has read the spinnof novels, what did you think about them, were they good? I would like to know so I can decide to read them or not.
