Useful Books for Civil Services Aspirants - To be read post exam

So this is my first post in this group. Most of us are currently waiting for results and this is also the year end. So any of you booklovers who have a annual target ( My target is 25 books / year , but wont exceed 12 books this year as well ) , can go for some of these books which are academically oriented and will help you in the exam, but are not exactly UPSC books. 

#1 Poor Economics : If you have to understand Poverty, Hunger, Malnutrition and why nations remain poor, this is the book to go for. I read it in 2013 and re-read it in 2019 again. Now that Abhijeet Banerjee has won a Nobel, it makes all the sense for you to go for it

#2 Sapiens : A mind blowing account of human evolution. If you need a reason to read this one, a former IAS Rank 1 told me that a significant part of his answers were influenced by this book. :) Not trying to sell you this book, but it is a great read.

#3 What ails the IAS and why it fails to deliver. This is a pleasant read and has several case studies you can quote in your answers. But donot read it just for exam sake. Read it because its a good read :)

#4 The Paradoxical Prime Minister . Baer with me as I reveal to you that this book is only one part political. The rest is - Current Affairs : ) Tharoor has come up with his views ( which means the opposition views ) on all issues that concern Indian Polity - right from Uniform Civil Code, to Finance Commission to role of Governors. A good read again!

#5 Reasons to Live. This book by Matt Haig is on depression and how to fight it. It does not exactly offer a solution, but is quite a solace. A good read for all those who have an extended tryst with the Civils.

Which one is your favourite?
