how can I get a copy of... Hullabaloo and the Guava Orchard?
Unfortunately OPL does not own Hullabaloo in the Guava Orchard (as you discovered!) and since it is an older book we can't purchase it, but you could request it through interlibrary loan--we borrow it from another library system for you. For more details on this process, look here. The only cost to you is the postage for sending the item back to the owning library.
I hope this helps!
