I love reading Unwind. It might be the most thrilling dystopian fiction I have read since The Hunger Games, and it sets the bar higher eversince. 
 The premise of Unwind is highly unlikely : Abortion is forbidden, but there is an option to 'unwind' troubled/unwanted children aged 13-18. That means sending them to a slightly more humane concentration camp, where the children's organs would be dissected and sold to strangers who can afford them. Think of people selling kidneys in illegal market, except that in Unwind the goods are more varied--they claim that 99% of unwound teenagers' organs would be used. And this has become legal. In-universe statistic claimed that one of every a hundred parents would think seriously to unwind their troubled teens and one from that number would actually do it. The odds multiplied with any additional children in the household. I know that human-trafficking and organ selling in black markets are true stories, but I would like to believe that the real-life has not grown that barbaric. 
 As unlikely as it is, Unwind kept me glued to the pages and turned me into a pile of emotional wreck. Neal Shusterman has successfully made me feel the anger, sadness, and hopelessness of the main characters. When I finished reading Unwind, I could not wait to get Unwholly, the next book in the series. 
 The problem is, the Bahasa Indonesia translation of Unwholly took AGES to be released. I know I could easily buy the English copy but this is not an option since my Unwind copy is in Bahasa Indonesia (Yeah, I am a bit OCD about which edition of books in the series I should buy). But lately this waiting has become too unbearable, so when I found out that there is an Unwind novella (published only in eBook format), eff this, I will get that. 
 Unstrung focused on Lev's story when he was separated from Connor and Risa. Out of the main characters, I found that Lev is the most complex and the hardest to understand. It is easier to put myself in Connor and Risa's shoes, most of their actions are driven by a desperate need to survive. However, Lev was a tithe, raised with a knowledge that he is going to be 'sacrificed' to God as soon as he is old enough to be unwind. He believed he was morally superior, considering that Connor and Risa have kidnapped him and prevent him to continue with his noble purpose of life. After a series of events, he managed to separate himself from Connor and Risa, and when he appeared before them again, he was not the same Lev they used to know. (view spoiler)[ We know a bit of Lev's heartbreaking journey with CyFy from Unwind but what exactly Lev has experienced to turn him from a meek tithe to a fierce suicide bomber, we haven't gotten to know. (hide spoiler)] This novella is supposed to fill the void in Lev's story. 
 The novella is okay in general. The story is a bit weak, especially compared with the previous book. I believe it would be somehow connected with Unwholly, but only loosely. There is some parts which make me shakes my head in disbelief, though. (view spoiler)[Like when it is explained that instead of using unwound body parts, the People of Chance/Native Americans used the organs of their spirit animal instead. And then they stated that the spirit animals could br anything, from insects to mountain lion. Then what if your spirit animal is -unfortunately- grasshopper, and then somehow you need a heart transplant? Would you receive a transplant of a grasshopper's heart? Gee, I would like to see how THAT works. (hide spoiler)] 
 This novella would not make sense if you haven't read Unwind before, so you might want to read at least Unwind first. 
 At the end, Shusterman gave us a glimpse of the Unwind excerpt...and the first chapter of Unwholly. HOW COULD HE DO THAT. SUCH A TEASE. ADDITIONAL ONE STAR FOR THAT, MR. SHUSTERMAN.
