Cyber Monday is here and deals are going fast! These deals are diaphanous. They are receding even as we speak, becoming mere memories of deals, prices longed for but lost, hints at what could have been had for less. A golden slant of sun through window falls on an empty countertop. Act now.

In 2011, at fourteen, I wrote my first novel-length manuscript in three weeks. When I looked up how to get published, I learned about literary agents and decided I wanted to do that, too.
What’s the lore behind choosing your career path ?

What if AI “sucks so much, steals the intellectual property of artists, and no one wants to use it or be around it or be around people who use it because we’re not all complete losers?” Mark O’Brien posts.
What if the A.I. bubble “is an inevitable part of developing and adopting a revolutionary tool that will fundamentally improve productivity and growth?” Mohamed El-Erian writes.

I spoke with a mother who had to take her whole family to a new country and leave their life behind so their trans daughter could grow up safely.
It's a story of the grief and difficulty around leaving, but also of the hope for the future in a new home.
Read it all through the link.

Just had my first “I was gonna offer on this, but the creator signed elsewhere and didn’t notify me in any way, just announced it on social media two weeks ago” experience. I’m a real literary agent now! Also, wow, this sucks.
