The firm will bring Avatar titles to the mass market in North America and Canada through its partner organisations Simon & Schuster and HarperCollins.
"The Avatar library is an excellent complement to the existing BOOM! list that doesn't cannibalise our Studios and KABOOM! offerings, but rounds out what we are already doing," said BOOM! founder and CEO Ross Richie.
"Avatars' CEO William Christensen is a brilliant businessman and has a proven track record of great Direct Market success. Avatar has great growth potential in the mass market book trade, and we look forward to being an excellent partner in their continued expansion."
Christensen added: "Distributing via BOOM!, Simon & Schuster, and HarperCollins Canada enables Avatar to bring its world-renowned, best-selling catalogue of the biggest creators in the business to a wider audience. Top talent like Alan Moore, Warren Ellis, and Garth Ennis continue to show sales growth and fan interest."
BOOM! joined forces with Simon & Schuster and HarperCollins Canada in July 2009. The company recently unveiled its new children's imprint Kaboom! and expanded its digital presence.
The publisher's partnership with Avatar is effective immediately.
