Hard Contact ... Lost Contact

Finally found my kids Halo trilogy in another Carefour book sale. I was there to find a copy of Hard Contact of the Republic Commando series. Don't get me wrong, I had a copy but now it just dissappeared from my library. I called up my brother, the only other guy I loaned my books to but he denied having it. Being a completist of sorts for SW novels. Im now in the midst of replacing that lost copy.
