so it turns out that mine eyes/brain have deceived me, and it was actually Suzie Townsend – another agent I’ve queried in the past (who according to The Rejection Book was very personable, but not the most tactful) – who is actively seeking submissions.
I considered submitting to Susannah Taylor anyway, as I plan to do it sometime, but my own experience of premature submissions has cautioned to wait until I feel that I’ve poured absolutely everything into the redraft.
