If we're talking about the same book, it is available for free: https://courses.csail.mit.edu/6.042/spring17/mcs.pdf https://courses.csail.mit.edu/6.042/spring17/mcs.pdf I bought the book for sale on Amazon. The printed version seems like a print-on-demand copy of the free PDF. The paper size is 8.5x11 and the layout is the same. I'm a little suspicious of the publisher. I have only used the book as a reference for a few sections. The style is very approachable.
