In today's #querytip I'm going to suggest you always explain what the plot complication is.
Ex of what NOT to do: 10 year old Jane and her dog, Spot, are on an adventure to save her father from a colony of gigantic Fire Ants, but things gets complicated!
Send agents 1 pitch at a time. Pick your strongest manuscript.
But also, list all your other books in the query too. Ex. "I also have a completed adult SF space opera & a horror available upon request."
I actually SIGNED A CLIENT on one of the OTHER books he listed.
