Early on I would always be reading one of the nikayas along with one or two other contemporary books.
I would recommend getting a copy of the Majjhima Nikaya to start. As far as specific contemporary books, just pick one. You'll like some and not like others, but it helps you get an idea about how you feel about the various approaches to the dhamma.
Through many of samsara’s births I hasten seeking, finding not the builder of this house - pain is birth again, again. O builder of this house you’re seen, you shall not build a house again, all your beams have given away, rafters of the ridge decayed, mind to the unconditioned gone, exhaustion of craving has it reached.(Dhp - 153, 154)
