$25 if you still haven't gotten your copy of ECHO POOL and you are ordering THOSE WHO HEAR, this deal will save you $4. Shipping is the most expensive part of our cost on these books, so if you would like both of them we can put them in one envelope and ship them at a reduced price. 2 books and shipping to any place on the planet for just $25. Or if you already have ECHO POOL and you have more than one young adult in your family order 2 copies of THOSE WHO HEAR for just $25. Simply be sure, when you make your payment, to let us know which combination you would like. Thanks for your support.
