特蕾西·基德（Tracy Kidder）撰写了着名的“保留的力量”一书。 Deogratias（Deo）是布隆迪人的故事。他离开布隆迪和卢旺达从种族灭绝中幸存下来，1993 – 1994年期间他到美国逃避在本国的暴力。基德讲述了这个故事，其形式是从迪奥逃离布隆迪之前和之后的时间之间摇摆。起初的这本书介绍了20世纪90年代在基督教徒胡图 – 图西族暴行的各个地点（Kidder，2009）对基德的重新审视。然后，这个故事转移到Deo从布隆迪到纽约来的闪回时期。在这里，读者意识到导致德奥离开布隆迪的种族灭绝和种族灭绝的背景。 Deo的挣扎时期也被解释为在纽约的移民。
Thesis statement: Are the life experiences of Deogratias ‘Deo’ are valuable enough for undermining or restoring the faith in humanity?
Tracy Kidder wrote the famous book Strength in What Remains. It is the story of Deogratias (Deo) a Burundian man. He left Burundi and Rwanda for surviving from genocide and he went to America for escaping himself from violence in his home country during 1993-1994. The story is narrated by Kidder in a format that swings between the times of before and after escape of Deo from Burundi. The book in the starting presents the revisit in 1990’s of Deo with Kidder in the various sites of Hutu-Tutsi atrocities (Kidder, 2009). The story then moves to flash back period in which Deo’s arrival to New York from Burundi is presented. Here the readers are made aware of the genocide and the backgrounds which leaded this genocide which provoked Deo to leave Burundi. The struggling period of Deo is also explained as an immigrant in New York.
Here the discussion will be done on “all the circumstances that surrounded Deo which were both the joys and horrors of his tale and do the story of Deo undermine or restore the faith in humanity”.
Kidder after meeting Deo and knowing his experiences and the effects of exodus and immigration on ordinary people decided to present this in a form of a story by following an example of life experiences of Deo. Kidder in this book had created a vivid picture of the experiences of genocide and what had happened and what may happen to an individual who is enduring it personally. The importance of fortuitous intervention is also illustrated by Kidder in an outstanding manner.
