I'm getting the same BS rejection as everybody else. If the advice was sincere, she'd have given some feedback in the body of the email. but the blatant copy and paste rejection shows that she's not even reading the sample writing. I would do yourself and your novel a favor and avoid this one.

I also wanted to point out that I got a less-than-24-hours form rejection that also, in the same email, offered their editorial services. I know they're UK and so not bound by AALA ethics, but this is a huge red flag and ethical violation because it gives the impression that the reason your work was rejected was because it needed editorial services, while also giving the impression that if you do pay for their editorial services, your work might be accepted in the future for representation.
Just to be clear, I've had this conversation in the past with Victoria Strauss of Writer Beware, and them offering editorial services in general is fine. But them offering editorial services on a rejected query is a big no no.

Quick on the rejection, offered me editorial services though. : ) I'm not sure if that is commentary on the state of the work, but there it is. My conclusion: Rugged times in a rugged business.

Thank you very much for sending us your work which we have read with interest. I’m afraid we don’t feel fully confident that this is something we could get behind with the total commitment it would need to do a good and effective job as its agent and therefore we are going to pass.

If you are interested in further feedback and editorial services please take a look at our Creative Writing Consultancy which offers exactly those things for new writers of fiction and non fiction.
