Tess Callero is one of the fabulous literary agents at Curtis Brown Ltd (another fabulous agent is Ginger Knowlton, my own agent). I got to know Tess when I recently did an Instagram takeover of the CB feed; the fact that I had so much FUN was largely due to Tess's enthusiasm and help - in addition to her role as an agent, Tess is also the Social Media Director at Curtis Brown.

You can find Tess on Twitter at @tesscallero, Curtis Brown on Instagram at @curtisbrown.ltd and on Twitter at @curtisbrownltd.
