You're right; the Schrödinger's equation induces a unitary time evolution, and it is deterministic. Indeterminism in Quantum Mechanics is given by another "evolution" that the wavefunction may experience: wavefunction collapse. This is the source of indeterminism in Quantum Mechanics, and is a mechanism that is still not well understood at a fundamental level (this is often called as "Measurement Problem").

If you want a book that talks about this kind of problems, I suggest you "Decoherence and the Appearance of a Classical World in Quantum Theory" by Joos, Zeh et al; it is a good book on this and more modern topics in Quantum Mechanics (e.g. how can the rules of Classical Mechanics, which are deterministic, can be obtained from QM). It's understandable with some effort, assuming you know basic things about Hilbert Spaces and the basic mathematical tools of QM.
