CAT 2016 - Suggest 1 Book To Prepare

Please suggest 1 book to prepare for CAT 2016.

I am an Engineer in the EPC industry, posted at an overseas project site. Carrying more than 1 book impractical due to luggage restrictions. I do not have access to decent Internet there.

At the most 2 books, of medium thickness.

Given work pressure, can realistically commit ~1-2 hours of daily studies.

Will return in September 2016, & move preparation to higher gear.

TIA

BUMP.

Kindly reply.

I need to buy the book[s] by Tuesday. Flying back on Wednesday.

My aim to buy this book is to decently familiarise myself with the nature of CAT, so that when I return in September 2016, I don't have to start from zero.

Awaiting guidance.

TIA
