Book after Modern Cosmology by Liddle

[shinobi20]

I just want to know what is the most logical next step after finishing the book Introduction to Modern Cosmology by Liddle? Some of the books that Liddle cited are

Advanced undergraduate:
Introduction to Cosmology by Matt Roos
Gravitation and Cosmology by Steven Weinberg (Undergrad!?)

Postgraduate:
Principles of Physical Cosmology by P. J. E. Peebles
Cosmological Physics by J. A. Peacock (Many bad reviews)
Modern Cosmology by S. Dodelson
Physical Foundations of Cosmology by V. Mukhanov

I have also read the book by Roos but I knida dislike it because I feel like there is poor organization of the materials and I found some errors but I can't find any errata so I can't completely trust his book. As for Mukhanov's book, I feel as though it requires QFT as background (I haven't taken QFT yet)? Can anyone advise me on this matter?

You could try Daniel Baumann's lecture notes for a cosmology course that he taught at Cambridge,

Isn't that too big of a leap? I think I can handle the first few parts but how about the perturbation part?
