More updates on this today. Publishers Weekly has an article with quotes from New Leaf Literary as well as former clients
here. A Twitter user has posted screencaps of Publishers Lunch Digest
here with further statements from NLL/Joanna Volpe.
Jordan Hamessley has also made a statement on twitter
here. A former client has commented on the Publishers Weekly article
here.
Do read it all yourself, but TL;DR: NLL's stance is that Hamessley parted ways with the agency amicably, and the authors/illustrators NLL let go with no offer of further support were "inactive" clients. If a client had negotiations or contracts, those are still being handled by NLL, either by placing that client with a different agent or as a temporary measure. If a client who was mid-negotiation was let go, NLL claims this is because Hamessley's records were not up to date.
Hamessley says she does not consider the split amicable and her records were up to date. The former client says she was terminated with no offer of support and had five active projects with Hamessley.
